The outbreak of COVID-19 across the U.S. has touched every facet of our society, and our democracy has been no exception.
The pandemic poses unique challenges with respect to the 2020 election, and several states have already rescheduled spring primaries for the summer. State election officials are weighing not only the public health concerns of in-person voting but also the possibility of voter disenfranchisement for those who would inevitably choose to stay home. Uncertainty surrounding the duration of the outbreak also raises concerns about voter safety for the general election in November.
This issue brief from The New Center discusses various state decisions, the state-specific provisions governing the postponement of elections, implications for the general election, and how a combination of drastically expanding mail-in voting alongside in-person voting may offer the best option to conduct a fair, secure, and inclusive 2020 election.
Which states have postponed their primaries?
Since President Trump's declaration of a national emergency over the coronavirus on March 13, Connecticut, Delaware, Georgia, Indiana, Kentucky, Louisiana, Maryland, New York, Ohio, Pennsylvania, Puerto Rico, Rhode Island, and West Virginia have postponed their primaries. Alaska, Hawaii, and Wyoming have replaced in-person primary voting with comprehensive mail-in systems. Ohio has postponed its primary and switched to a nearly all-mail election, with in-person voting allowed for people with disabilities and those without mailing addresses.
Despite the national emergency, three states, Arizona, Florida, and Illinois held their primaries on March 17 as scheduled. Wisconsin will hold its primary as scheduled on April 7, but on March 27, Governor Tony Evers requested that the state send absentee ballots to all 3.3 million voters—a task some state legislators and election clerks claim to be logistically impossible within such a short time frame. Several groups have filed lawsuits seeking to postpone the election and extend the deadline for absentee voting.
What legal provisions govern the postponement of a primary election?
The process involved in delaying a primary election varies by state, and some states are better prepared than others to modify their elections in emergency situations. A handful of states have statutes that allow for the postponement of an election in case of an emergency, and most of these statues grant unilateral decision making power to the governor.
Other states, such as Pennsylvania, do not have legislation on the books explicitly addressing election postponement. And state law sets Pennsylvania's primary election date for the fourth Tuesday in April in a presidential election year. Postponement of the Pennsylvania primary required the passage of a bill to amend the election code, and this would also be the case for any other primary with a date set by law.
A similar lack of clear guidelines for postponing elections caused confusion in Ohio and shed light on the importance of emergency contingency plans. The Ohio Democratic primary was scheduled for Tuesday, March 17. On Monday the 16th, Governor Mike DeWine expressed his desire to delay the in-person election and extend absentee voting due to the coronavirus outbreak. Without the authority to unilaterally postpone an election, he promised to support a lawsuit asking the Franklin County Court of Common Pleas to exercise its power to do so. Judge Richard A. Frye rejected the lawsuit, claiming that the last-minute postponement would set a "terrible" precedent.
Shortly after, DeWine's chief health adviser declared a public health emergency and ordered the polls to close. This prompted a lawsuit from the Ohio Democratic Party. "Nothing in Ohio law provides that Respondent Secretary has the power to set the date of Ohio's 2020 presidential primary election," says the lawsuit. "Instead, the legal authority to set the date of Ohio's 2020 presidential primary election rests with the Ohio General Assembly." The Ohio Supreme Court denied this legal challenge. In addition to officially postponing the election to April 28, Ohio has also decided that the rescheduled primary will be conducted almost exclusively by mail.
If the outbreak extends through the fall, can the November general election be postponed?
The general election could theoretically be postponed, but several obstacles make this scenario highly unlikely. The Presidential Election Day Act, passed in 1845, sets Election Day as "the Tuesday next after the first Monday in the month of November." Therefore, postponing election day would require Congress to pass legislation that would be signed by the president and upheld in the courts.
In the unlikely case that this would happen, any flexibility in determining the length of the election delay would be limited by the Constitution. The 20th Amendment states that "The terms of the President and the Vice President shall end at noon on the 20th day of January… of the years in which such terms would have ended if this article had not been ratified; and the terms of their successors shall then begin."
What about mail-in voting for the general election?
While postponing the general election is effectively out of the question, voting by mail is one potential solution that could allow elections to continue while also prioritizing public health. While states do not have the power to change the date of their general elections, they do have broad jurisdiction to decide how to conduct them. Several states have expanded absentee voting options to some degree or adopted universal mail-in primaries, which can serve as "test runs" for expansive mail-in voting in the general election. And five states, Colorado, Hawaii, Oregon, Washington, and Utah, automatically mail ballots to all registered voters for all elections. An additional 28 states offer "no-excuse" absentee voting, which means voters may vote by mail for any reason if they request a ballot in advance. The remaining 17 states offer absentee voting to those with valid excuses. Voters with injuries or illnesses qualify, as do those who will be out of the country on election day.
For the states that do not automatically mail ballots to all voters, uncertainty surrounding the outbreak's timeline has led state and local election boards to mobilize in preparation for a surge in demand for general election absentee ballots. But some leaders have hesitated to support the changes that would be involved. Democrats have traditionally been eager proponents of expanded absentee voting, which Republicans have dismissed as partisan power grabs. However, evidence does not support the belief that mail-in voting offers an unfair advantage to Democrats. In the 2016 presidential election, the rates of mail-in voting for Democrats and Republicans were about the same. If the coronavirus outbreak necessitates a nationwide move to mail-in voting, state election officials will have to weigh several logistical and substantive concerns:
Costs and Logistical Hurdles
The Brennan Center estimates that it would cost about $1.4 billion to implement nationwide mail-in voting for the general election. This estimate includes the cost of postage, ballot printing, and other equipment necessary for the transition. Maintaining in-person elections, bolstering online voter registration, and educating the public on these new measures would increase the overall cost of adequate general election preparation to about $2 billion. The $2 trillion coronavirus relief package includes a fraction of this estimated cost—$400 million—to help the states expand mail-in voting and make other election preparations.
Expanding mail-in voting cannot happen overnight. States that wish to make significant changes to their voting systems have a short window of time to do so before the November elections. And the more ballots states need to mail, the more time they will typically need. They will also need to hire and train new workers, verify voter mailing addresses, print ballots, mail them well in advance of the voting deadline, use signature-matching technology to validate them once they return, build in time to rectify any issues that may arise with signature matching, and count the votes. It will be up to each state to balance public health, election security, and feasibility when determining how to prepare for the general election.
While mail-in voting facilitates participation for many, it creates barriers for others when it is the only option. Many voters are comfortable with the civic experience of casting a ballot at a local polling place and might choose not to vote at all if absentee voting is the only option. Postal delivery is less convenient for voters who live in certain rural areas or who rely on P.O. boxes that are not necessarily nearby. And many Native Americans on reservations do not receive mail at all. For non-English speakers, translated instructions on a mailed ballot might not be as useful as a bilingual poll worker who can answer specific questions in person.
While voter fraud is rare, mail-in voting is more prone to it than other voting methods. For example, "ballot harvesting" scandals involve the altering of absentee ballots by volunteers or other political operatives who are tasked with collecting and submitting these ballots on behalf of voters. States scrambling to expand their mail-in voting systems might be more prone to these issues than others with robust mail-in voting systems that have been developed over the course of several years.
Certain precautions can help prevent this type of fraud by making it more convenient for voters to deliver ballots on their own. Tammy Patrick, a former county election official who is now a senior adviser at the nonprofit Democracy Fund, suggests that states offer prepaid return postage, accept ballots postmarked as late as election day, and designate convenient drop-off locations for voters who prefer to deliver their ballots in person.
"If you do these things, no one needs to pick up your ballot—it's convenient for voters to maintain power and authority over their own ballot. Not doing these things risks a situation where a voter has waited until the last day, and someone shows up at their door offering to take their ballot and they see it as their last opportunity. That could be someone with good intentions or not," Patrick told ProPublica.
Another security issue that could be amplified with the adoption of universal mail-in voting is voter coercion, which occurs when family members or others exert pressure on voters to vote a certain way. While all voters can be susceptible to coercion, absentee voters are especially prone—the kitchen table does not provide the same degree of freedom to vote independently as the voting booth does. But the same measures that would help prevent ballot tampering by making the process more seamless might also be useful in thwarting coercion efforts. For example, averting family scrutiny becomes easier when you have the option to return your ballot in a prepaid envelope and avoid having to provide postage from home.
Expansive mail-in voting systems and secure elections are not mutually exclusive as long as voters have plenty of options and privacy is prioritized. Colorado, which has one of the most secure mail-in voting systems in the country, maintains the option to vote in-person. An in-person vote voids that voter's mailed ballot.
Suggested Best Practices for States
When it comes to elections, there is no one-size-fits-all reform that would work for all 50 states. Many states did make changes to their primaries that prioritize both the health of the public and the integrity of the election. Even without postponement as an option for the general election in November, states still have the opportunity to make meaningful changes if they act quickly. To the extent that it is feasible, each state should consider the possibility that the coronavirus outbreak will continue through the fall and make in-person voting too dangerous.
Expand mail-in voting options
States should mobilize to change their voting procedures in a way that offers mail-in voting to as many eligible voters as possible. States that currently require an excuse to vote absentee should eliminate these requirements and allow any voter to request an absentee ballot online. States that already offer "no-excuse" absentee voting should move in the direction of the few states that automatically send ballots to all eligible voters.
Enact measures to secure mail-in elections
States should work to implement identity verification measures, such as signature-matching technology, for their mail-in ballots while also planning to rectify inevitable technical issues that might incorrectly invalidate some ballots. To combat ballot tampering as well as the increased likelihood of voter coercion that expanded absentee voting can bring, states should enact precautionary measures that promote and facilitate ballot delivery by the voters themselves rather than a third party. These include offering prepaid postage, accepting ballots postmarked as late as election day, and setting convenient drop-off locations for in-person delivery. Removing any opportunity for a third party to intercept the ballots or observe the votes of others can help preserve election integrity. Exceptions for elderly or disabled voters in need of assistance are often appropriate, but third-party assistance in these cases should require some extra form of authentication.
Maintain the option to vote in person
While states should encourage as much absentee voting as possible to protect the health of their voters and poll workers, they should also retain the option to vote in person to give everyone a fair chance to participate. While health concerns about crowds at the polls are valid, expanded absentee voting should reduce the number of voters who show up. To reduce crowds even further, states should consider adding new polling locations if possible.
Retaining an in-person voting option would expand voter access and serve as another layer of protection against fraud or coercion. With this option, a voter who is not satisfied with the absentee ballot they submitted can invalidate it by going to the polls on election day and casting a new one. A system of expanded mail-in voting alongside traditional, in-person voting is likely the best way to promote both public health and participation in the democratic process amid this unprecedented public health crisis.

The vast majority of SARS-CoV-2 transmission occurs indoors, most of it from the inhalation of airborne particles that contain the coronavirus. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. But this is hard to do when an estimated 40% of cases are asymptomatic and asymptomatic people can still spread the coronavirus to others.
It’s All About Fresh, Outside Air<p>The safest indoor space is one that constantly has lots of <a href="https://www.epa.gov/indoor-air-quality-iaq/how-does-outdoor-air-enter-building" target="_blank">outside air</a> replacing the stale air inside.</p><p>In commercial buildings, <a href="https://www.ncbi.nlm.nih.gov/books/NBK143277/" target="_blank">outside air is usually pumped in</a> through heating, ventilating and air-conditioning (HVAC) systems. In <a href="https://www.epa.gov/indoor-air-quality-iaq/how-does-outdoor-air-enter-building" target="_blank">homes, outside air gets in</a> through open windows and doors, in addition to seeping in through various nooks and crannies.</p><p>Simply put, the more fresh, outside air inside a building, the better. Bringing in this air dilutes any contaminant in a building, whether a virus or a something else, and <a href="https://doi.org/10.1111/j.1600-0668.2010.00703.x" target="_blank">reduces the exposure of anyone inside</a>. Environmental engineers like me quantify how much outside air is getting into a building using a measure called the <a href="https://doi.org/10.1038/jes.2013.30" target="_blank">air exchange rate</a>. This number quantifies the number of times the air inside a building gets replaced with air from outside in an hour.</p><p>While the exact rate depends on the number of people and size of the room, most experts consider roughly <a href="https://doi.org/10.1034/j.1600-0668.2002.01145.x" target="_blank">six air changes an hour</a> to be good for a 10-foot-by-10-foot room with three to four people in it. In a pandemic this should be higher, with one study from 2016 suggesting that an exchange rate of nine times per hour <a href="https://doi.org/10.1177%2F1420326X16631596" target="_blank">reduced the spread of SARS, MERS and H1N1</a> in a Hong Kong hospital.</p><p>Many buildings in the U.S., <a href="https://doi.org/10.1111/ina.12403" target="_blank">especially schools</a>, do not meet recommended ventilation rates. Thankfully, it can be pretty easy to get more outside air into a building. Keeping <a href="https://doi.org/10.1016/S0960-1481(99)00012-9" target="_blank">windows and doors open</a> is a good start. Putting a box fan in a window blowing out can greatly increase air exchange too. In buildings that don't have operable windows, you can change the mechanical ventilation system to increase how much air it is pumping. But in any room, the more people inside, the faster the air should be replaced.</p>
Using CO2 to Measure Air Circulation<p>So how do you know if the room you're in has enough air exchange? It's actually a pretty hard number to calculate. But there's an easy-to-measure proxy that can help. Every time you exhale, you <a href="https://doi.org/10.1111/ina.12383" target="_blank">release CO2</a> into the air. Since the coronavirus is most often spread by breathing, coughing or talking, you can use <a href="https://pdfs.semanticscholar.org/dd7e/b2870c38f70e5285e5118ed6f158c091f7cf.pdf" target="_blank">CO2 levels</a> to see if the room is filling up with potentially infectious exhalations. The CO2 level lets you estimate if enough fresh outside air is getting in.</p><p>Outdoors, CO2 levels are just above 400 parts per million (ppm). A well ventilated room will have around <a href="https://doi.org/10.1111/j.1600-0668.1999.00003.x" target="_blank">800 ppm of CO2</a>. Any higher than that and it is a sign the room might need more ventilation.</p><p>Last year, researchers in Taiwan reported on the <a href="https://doi.org/10.1111/ina.12639" target="_blank">effect of ventilation on a tuberculosis outbreak</a> at Taipei University. Many of the rooms in the school were underventilated and had CO2 levels above 3,000 ppm. When engineers improved air circulation and got CO2 levels under 600 ppm, <a href="https://doi.org/10.1111/ina.12639" target="_blank">the outbreak completely stopped</a>. According to the research, the increase in ventilation was responsible for 97% of the decrease in transmission.</p><p>Since the coronavirus is spread through the air, higher CO2 levels in a room likely mean there is a <a href="https://doi.org/10.1111/ina.12639" target="_blank">higher chance of transmission</a> if an infected person is inside. Based on the study above, I recommend trying to keep the CO2 levels below 600 ppm. You can buy <a href="https://doi.org/10.5194/amt-7-3325-2014" target="_blank">good CO2 meters</a> for around $100 online; just make sure that they are accurate to within 50 ppm.</p>
Air Cleaners<p>If you are in a room that can't get enough outside air for dilution, consider an air cleaner, also commonly called air purifiers. These machines remove particles from the air, usually using <a href="https://doi.org/10.1016/j.cap.2005.07.013" target="_blank">a filter</a> made of tightly woven fibers. They can <a href="https://shellym80304.files.wordpress.com/2020/06/miller-leiden-et-al-1996.pdf" target="_blank">capture particles containing bacteria and viruses</a> and can help reduce disease transmission.</p><p>The U.S. Environmental Protection Agency says that <a href="https://www.epa.gov/coronavirus/air-cleaners-hvac-filters-and-coronavirus-covid-19" target="_blank">air cleaners can do this for the coronavirus</a>, but not all air cleaners are equal. Before you go out and buy one, there are few things to keep in mind.</p><p>The first thing to consider is <a href="https://shellym80304.files.wordpress.com/2020/06/air-cleaner-report.pdf" target="_blank">how effective an air cleaner's filter is</a>. Your best option is a cleaner that uses a high-efficiency particulate air (<a href="https://doi.org/10.1016/S0021-8502(05)80214-9" target="_blank">HEPA</a>) filter, as these remove more than <a href="https://doi.org/10.1063/1.2771421" target="_blank">99.97% of all particle sizes</a>.</p><p>The second thing to consider is how powerful the cleaner is. The bigger the room – or the more people in it – the more air needs to be cleaned. I worked with some colleagues at Harvard to put together a tool to help teachers and schools determine <a href="https://docs.google.com/spreadsheets/d/1NEhk1IEdbEi_b3wa6gI_zNs8uBJjlSS-86d4b7bW098/edit#gid=1275403500" target="_blank">how powerful of an air cleaner you need for different classroom sizes</a>.</p><p>The last thing to consider is the validity of the claims made by the company producing the air cleaner.</p><p>The Association of Home Appliance Manufacturers certifies air cleaners, so the AHAM Verifide seal is a good place to start. Additionally, the California Air Resources Board has a <a href="https://ww2.arb.ca.gov/our-work/programs/air-cleaners-ozone-products/california-certified-air-cleaning-devices" target="_blank">list of air cleaners</a> that are certified as safe and effective, though not all of them use HEPA filters.</p>
Keep Air Fresh or Get Outside<p>Both the <a href="https://www.who.int/news-room/commentaries/detail/transmission-of-sars-cov-2-implications-for-infection-prevention-precautions" target="_blank">World Health Organization</a> and <a href="https://www.cdc.gov/coronavirus/2019-ncov/daily-life-coping/deciding-to-go-out.html" target="_blank">U.S. Centers for Disease Control and Prevention</a> say that poor ventilation increases the risk of transmitting the coronavirus.</p><p>If you are in control of your indoor environment, make sure you are getting enough fresh air from outside circulating into the building. A CO2 monitor can help give you a clue if there is enough ventilation, and if CO2 levels start going up, open some windows and <a href="https://www.advisory.com/daily-briefing/2020/07/17/outdoor-gathering" target="_blank">take a break outside</a>. If you can't get enough fresh air into a room, an air cleaner might be a good idea. If you do get an air cleaner, be aware that they don't remove CO2, so even though the air might be safer, CO2 levels could still be high in the room.</p><p>If you walk into a building and it feels hot, stuffy and crowded, chances are that there is not enough ventilation. Turn around and leave.</p><p>By paying attention to air circulation and filtration, improving them where you can and staying away from places where you can't, you can add another powerful tool to your anti-coronavirus toolkit.</p>

The tiny island nation of Mauritius, known for its turquoise waters, vibrant corals and diverse ecosystem, is in the midst of an environmental catastrophe after a Japanese cargo ship struck a reef off the country's coast two weeks ago. That ship, which is still intact, has since leaked more than 1,000 metric tons of oil into the Indian Ocean. Now, a greater threat looms, as a growing crack in the ship's hull might cause the ship to split in two and release the rest of the ship's oil into the water, NPR reported.
On Friday, Prime Minister Pravind Jugnauth declared a state of environmental emergency.
France has sent a military aircraft carrying pollution control equipment from the nearby island of Reunion to help mitigate the disaster. Additionally, Japan has sent a six-member team to assist as well, the BBC reported.
The teams are working to pump out the remaining oil from the ship, which was believed to be carrying 4,000 metric tons of fuel.
"We are expecting the worst," Mauritian Wildlife Foundation manager Jean Hugues Gardenne said on Monday, The Weather Channel reported. "The ship is showing really big, big cracks. We believe it will break into two at any time, at the maximum within two days. So much oil remains in the ship, so the disaster could become much worse. It's important to remove as much oil as possible. Helicopters are taking out the fuel little by little, ton by ton."
Sunil Dowarkasing, a former strategist for Greenpeace International and former member of parliament in Mauritius, told CNN that the ship contains three oil tanks. The one that ruptured has stopped leaking oil, giving disaster crews time to use a tanker and salvage teams to remove oil from the other two tanks before the ship splits.
By the end of Tuesday, the crew had removed over 1,000 metric tons of oil from the ship, NPR reported, leaving about 1,800 metric tons of oil and diesel, according to the company that owns the ship. So far the frantic efforts are paying off. Earlier today, a local police chief told BBC that there were still 700 metric tons aboard the ship.
The oil spill has already killed marine animals and turned the turquoise water black. It's also threatening the long-term viability of the country's coral reefs, lagoons and shoreline, NBC News reported.
"We are starting to see dead fish. We are starting to see animals like crabs covered in oil, we are starting to see seabirds covered in oil, including some which could not be rescued," said Vikash Tatayah, conservation director at Mauritius Wildlife Foundation, according to The Weather Channel.
While the Mauritian authorities have asked residents to leave the clean-up to officials, locals have organized to help.
"People have realized that they need to take things into their hands. We are here to protect our fauna and flora," environmental activist Ashok Subron said in an AFP story.
Reuters reported that sugar cane leaves, plastic bottles and human hair donated by locals are being sewn into makeshift booms.
Human hair absorbs oil, but not water, so scientists have long suggested it as a material to contain oil spills, Gizmodo reported. Mauritians are currently collecting as much human hair as possible to contribute to the booms, which consist of tubes and nets that float on the water to trap the oil.

There are trillions of microplastics in the ocean — they bob on the surface, float through the water column, and accumulate in clusters on the seafloor. With plastic being so ubiquitous, it's inevitable that marine organisms, such as sharks, will ingest them.
Polyproylene fibers found in one of the sampled sharks. Kristian Parton
Spiny dogfish. NOAA / Wikimedia Commons<p>"There appear to be two routes for these particles to end up in the sharks," Parton said. "The first through their food source [such as] crustaceans. Their prey may already contain these fibers, and consequently it's passed to the shark through bioaccumulation up the food chain. The second pathway is direct ingestion from the sediment. As these sharks feed, they'll often suck up sediment into their mouths, some of this is expelled straight away, although some is swallowed, therefore fibers and particles that may have sunk down into the seabed may be directly ingested from the surrounding sediment as these sharks feed."</p><p>Some sharks only contained a few plastic particles, but others contained dozens. The larger the shark, the more plastic was in it, the findings suggested. The highest number of microplastics was found in an individual bull huss, which had 154 polypropylene fibers inside its stomach and intestines.</p><p>"It's perhaps likely this individual shark had swallowed a larger piece of fishing rope/netting and this has broken down during digestive processes within the shark, and also broken down into smaller pieces during our analysis," Parton said.</p>
Lesser-spotted dogfish caught as bycatch. Kristian Parton<p>While this study only examined the stomach and digestive tracts of demersal sharks, Parton says it's possible that plastic would be present in other parts of the sharks' bodies, such as the liver and muscle tissue. However, more research would be needed to prove this.</p><p>At the moment, there is also limited understanding of how microplastic ingestion would impact a shark's health, although microplastics are known to negatively influence feeding behavior, development, reproduction and life span of zooplankton and crustaceans.</p><p>"If we can show that these fibers contain inorganic pollutants attached to them, then that could have real consequences for these shark species at a cellular level, impacting various internal body systems," Parton said.</p>
Parton in the lab. Kristian Parton<p>This new study demonstrates how pervasive and destructive plastic pollution can be in the marine environment, according to Will McCallum, head of oceans for Greenpeace U.K.</p><p>"Our addiction to plastics combined with the lack of mechanisms to protect our oceans is suffocating marine life," McCallum said in a statement. "Sharks sit on top of the marine food web and play a vital role in ocean ecosystems. Yet, they are completely exposed to pollutants and other human impactful activities. We need to stop producing so much plastic and create a network of ocean sanctuaries to give wildlife space to recover. The ocean is not our dump, marine life deserves better than plastic."</p>

After a Japanese-owned oil tanker struck a reef off Mauritius on July 25, a prolonged period of inaction is threatening to become an ecological disaster.

How to Tackle Oil Spills<p>The method for tackling oil spills depends on several factors, including the type and amount of oil in question, location and weather conditions.</p><p>"Once the oil comes to shore, the more intensive the cleaning technique. You can risk causing further damage," said Nicky Cariglia, an independent consultant at Marittima, who specializes in marine pollution. </p><p>"If you wanted to remove all traces of oil, the techniques available become increasingly aggressive the less oil that remains. In mangroves, you would have the added risk of causing damage by trampling," Cariglia told DW. Highly sensitive mangrove ecosystems line the Mauritius east coast that is threatened by the current spill.</p><p>Because oil normally has a lower density than water, it floats on the surface of the ocean. This means that for clean-up action to be most effective, it should happen very quickly after a spill, before the oil disperses. </p>
