Some states have almost completely moved to voting by mail or early voting, whereas other states mostly vote in person on election day. For the Washington Post, Nick Mourtoupalas used a grid map to show how voting method changed each election since 2016.
Here in California, I voted by mail the last election, but I had no idea the percentages were that high. I’m also surprised by the high rates of early voting.
The estimates are based on data from the Election Administration and Voting Survey, which has run every two years since 2004.
