As voters went to the polls Tuesday across the country, they encountered an array of precautions meant to keep the presidential election from becoming a Covid-19 superspreader event. Masks and hand sanitizer were ubiquitous, of course, as was grousing about masks. In New York, some polling places handed out individual pens for voting, while others cleaned off markers in between each use. In one Ohio county, each person was given a plastic glove to wear while handling their ballot. And in a number of states, people too afraid to get out of their cars and stand in a socially distanced line could vote curbside, as if they were picking up takeout.
