In an historic year for voter turnout, 2020 also underscored the power and importance of mailed-out ballots. In the top 10 states for highest turnout among eligible voters, half are full vote-at-home states. The remaining five states implemented same-day registration and put temporary policies in place making it easier to access a mail ballot. Conversely, the bottom 10 states cut off voter registration four weeks before Election Day and enforced excuse requirements for mail ballots.
