To vote absentee by mail, first you’ll need to apply for an absentee ballot (click here) no later than July 22nd at 5:00 pm. Then, when you complete your absentee ballot, it must be received by election day.

Whether it’s in-person or by-mail, you’ll need to give an excuse to vote by absentee ballot. Info here on what qualifies.
