Although most people in the U.S. usually vote in person, not everyone can. For instance, many members of the U.S. military will be away from home. That’s why some form of mail-in, or absentee, voting is allowed in every state and Washington, D.C. And five states hold their elections almost entirely by mail.
Due to concerns about Covid-19, more Americans than ever are expected to vote by mail this year to avoid crowded polling places. President Donald Trump has suggested that mail-in voting could lead to voter fraud, or people voting more than once. But studies have shown that fewer than 1 percent of votes in the 2016 presidential election resulted in fraud.
“It’s actually really, really rare because most people aren’t going to risk going to jail for five years to cast one fake vote,” says Wehle.
