As the United States prepares to hold an election during a pandemic, the country is expecting an unprecedented number of people to vote by mail as states move to make it easier for people to vote without going to an in-person polling place.
Rules and procedures vary from state-to-state, with some sending actual ballots to every registered voter, some states sending people absentee ballot applications rather than the ballots themselves and other states requiring people to go online or to an election office to get an absentee ballot application. Some states before 2020 already ran universal mail-in elections quite successfully.
Deadlines for ballots to applied for and sent and received by election officials also vary by state.
Below is an overview of states that either this year or previously have moved to the two most permissive forms of mail balloting -- universal mail-in voting and sending absentee ballots applications to all voters.
