You can make a one-time request for an absentee ballot or you can request an absentee ballot for all elections. If you choose to receive a ballot for all elections, you're on the list for good! The only way your status would drop is if you move and do not notify the elections office. You must be a registered voter to request an absentee ballot.
If Election Day is growing near and you still have not received your ballot in the mail, contact your local election office. They'll be able to look you up and provide you with your voting options. The deadline to request an absentee ballot is 12:00 noon the day before the election, and the deadline to submit your voted absentee ballot is 8:00 p.m. on Election Day.
Ballots must be received (not postmarked) by 8:00 p.m. on Election Day. If you return your ballot by mail, the US Postal Service recommends mailing your ballot at least one week prior to Election Day. You may also return your ballot in-person to your county elections office, or drop it off at any polling place in your county on Election Day.
