At Tuesday’s presidential debate, President Donald Trump complained that poll watchers in Philadelphia were denied access to early voting in the critical battleground state.“I’m urging my supporters to go into the polls and watch very carefully because that’s what has to happen,” Trump said. “I am urging them to do it. As you know, today there was a big problem. In Philadelphia, they went in to watch. They’re called poll watchers, a very safe, very nice thing. They were thrown out. They weren’t allowed to watch. You know why? Because bad things happen in Philadelphia. Bad things.”Poll watching is generally a commonly-accepted democratic practice employed throughout the US. But there are questions on what constitutes a polling site.In Pennsylvania, voting centers are not considered polling locations. Early voting centers are locations where voters can pick up a mail-in ballot and can complete and return the ballot on-site. Voters have the option of taking the ballot home and returning it before the election.“We don’t give someone a poll watcher certificate to … watch somebody fill out their ballot at their kitchen table,” Republican Philadelphia City Commissioner Al Schmidt told the Philadelphia Inquirer.While poll-watching laws vary by state, the practice is generally accepted, but it has limits. According to the National Conference of State Legislatures, poll watchers are to take a hands-off approach.For instance, poll watchers should not talk to voters, interfere with the voting process or campaign while on-site. Poll watchers, however, can watch for irregularities and report them to elections officials and political campaigns.There are generally limits on the number of poll watchers a campaign or party can designate. An accreditation process in 40 states means an ordinary citizen cannot walk into a polling site without some level of training, according to the Carter Center. "This process is led by local party chairs, candidates, or ballot issue groups and can require approval by election officials or the secretary of state’s office," the Carter Center said.Some interpreted Trump’s call for poll watchers as a voter intimidation tactic."Trump also told 'his supporters' to 'go into the polls and watch very carefully,'" said Nevada Attorney General Aaron Ford on Twitter. "But he wasn't talking about poll watching. He was talking about voter intimidation. FYI, voter intimidation is illegal in Nevada. Believe me when I say it: You do it, and you will be prosecuted."A hands-off approach is what differentiates someone engaging in legal poll watching and illegal voter intimidation. While poll watching laws are regulated at the state level, there is a federal law against voter intimidation.“Whoever intimidates, threatens, coerces, or attempts to intimidate, threaten, or coerce, any other person for the purpose of interfering with the right of such other person to vote or to vote as he may choose, or of causing such other person to vote for, or not to vote for, any candidate for the office of President, Vice President, Presidential elector, Member of the Senate, Member of the House of Representatives, Delegate from the District of Columbia, or Resident Commissioner, at any election held solely or in part for the purpose of electing such candidate, shall be fined under this title or imprisoned not more than one year, or both,” the law reads.To learn more about each state’s laws on poll watching, click here.Justin Boggs is a writer for the E.W.

As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017

As students return to school and employees head back to the office all with new safety protocols likely including wearing a mask, a new study from Duke University explores which masks are more effective.Spoiler alert: A fitted N95 mask, usually reserved for those in the medical community, performed the best in their test. However, since many Americans do not have access to those and have been using a mix of store-bought or homemade cotton and fabric facial coverings, Duke tested 13 other kinds of masks.The study, which was published Friday, was prompted when a professor at Duke’s School of Medicine was asked to assist a local group buying masks in bulk for the community. According to CNN, the professor wanted to make sure the masks they bought were effective.Researchers gathered 14 kinds of masks, including the professionally-fitted N95 mask, a bandana, homemade cotton varieties, and a surgical mask. They then used a dark room, laser beam and cell phone camera to record how many droplets (which reflect the laser beam light) each mask allows through.For each mask test and the non-mask wearing control test, the speaker was recorded saying “Stay healthy, people” five times. Each mask was tested ten times. 1229

As the chaotic 2020 presidential race enters its final stretch, Vice President Mike Pence and Democratic vice presidential nominee Kamala Harris will square off in a debate at 9 p.m. ET on Wednesday in Salt Lake City.The COVID-19 pandemic will be at the forefront of Wednesday's debate — both literally and figuratively. As the nation seeks more info regarding President Donald Trump's health amid his COVID-19 infection, both Pence and Harris have agreed to allow debate officials to install plexiglass shields next to their podiums.Harris' staff initially requested the shields, citing the COVID-19 outbreak that's infected several White House staffers. After initially saying the shields were not necessary, Pence's staff agreed to the change on Tuesday night.The Associated Press reports that both Harris and Pence tested negative for the virus on Tuesday morning.Wednesday's debate will be broken into nine 10-minute segments. Each candidate will have two minutes to answer a question from moderator Susan Page, and the other candidate will then have two minutes to respond.The 2020 VP debate will likely hold more important than in years past, given the ages of Trump and his opponent, former Vice President Joe Biden. Trump, 74, was the oldest candidate ever to be elected president in 2016, and Biden, 77, is three years older than Trump. Amid a global pandemic, voters may be taking a keen interest in each administration's chain of command.The Trump campaign is banking on a strong performance from Pence amid slumping poll numbers. An average of national polls shows Biden leading Trump by about nine percentage points, and a recent CNN poll released this week showed that 57% of likely voters favored Biden, compared to just 41% for Trump.Wednesday may also mark the last debate for at least a few weeks. There are two more presidential debates scheduled between now and Nov. 3, but Trump's COVID-19 diagnosis has put the status of the second debate — currently scheduled for a week from Thursday — in doubt. Trump says he still plans to participate, but Biden has said the debate should not take place if the president is still infected with the virus due to safety concerns. 2196
