Before making a decision on how you'll cast your vote in this presidential election, make sure you know how your state handles mail-in ballots.
Election Day is less than two weeks away on Nov. 3, so if you haven't figured out how you'll vote, now's the time: in person on election day, through early in-person voting or with a mail-in ballot. Every state offers some form of voting by mail, but the rules for who gets to cast a mail-in ballot -- and the steps you'll need to follow -- vary from state to state.
For example, a handful of states have automatically sent an absentee ballot to each registered voter. Others require voters to apply for a mail-in ballot, citing a reason why they can't show up in person to vote. And a few require a witness to observe the voter marking a mail-in ballot. In between are "no-excuse" states that will send a mail-in ballot to a voter who requests one for any reason.
As a result of the ongoing coronavirus pandemic, up to 50% of voters are estimated to cast their ballot by mail as one measure to keep from spreading or acquiring COVID-19. Absentee voting is already on the rise, growing from 7.8% in 1996 and to nearly 21% in 2016, according to Pew Research Center. (If you do vote in person, here's how to stay safe.)

Knowing how your state will treat mail-in ballots can help you plan how you'll vote this year.
Alabama: Prior to 2020, the state required an excuse to vote by mail, such illness. For a July run-off election, a judge blocked that requirement, and for the general election, the state issued an emergency rule that allows any qualified voter to request an absentee ballot.
Alaska: The state is taking steps to ensure voters and polling station workers stay safe for this election this year, including giving voters masks and gloves. For its August primary and November general elections, anyone can request a mail-in ballot. The state requires a witness to observe a voter signing the absentee ballot.
Arizona: The state is one of many that offers no-excuse absentee voting, which means any Arizonan can request a one-time or permanent mail-in ballot without needing to give a reason.
Arkansas: To vote by mail, you need to request an absentee ballot with an excuse why you can't vote in person, such as illness or physical disability. The state's Board of Election Commissioners said concern about COVID-19 is a valid excuse to request an absentee ballot.
California: For the November general election the state will send a mail-in ballot to all registered voters prior to the election. Normally, California voters would need to request a mail-in ballot. Polling places will also be open for those who want to vote in person, from Oct. 31 to Nov. 3.

Iowa: Any Iowa registered voter can request an absentee ballot without a reason.
Kansas: The state lets any registered voter vote by mail using what it calls "an advance by mail ballot."
Kentucky: For the general election this fall, any registered voter can request an absentee ballot. In preceding election cycles, voters needed an excuse to vote by mail.
Louisiana: In Louisiana, you are required to have an excuse, such as age or hospitalization, to vote by mail.

Maine: Another no-excuse state, any registered voter can cast an absentee ballot instead of voting in person.
