Early Voting + Absentee Voting
Early Voting Dates: Varies by County to March 9th
You can vote in person at your local election authority through March 9th at 5:00 p.m. before the election, using an absentee ballot. Visit your local election authority’s website for start date.
To vote absentee by mail, first you’ll need to apply for an absentee ballot (click here) no later than Feb 26th at 5:00 pm. Then, when you complete your absentee ballot, it must be postmarked by the day before the election. If you have not voted in-person at your current address, you’ll need to submit a copy of your photo I.D. with address and signature with your ballot.
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.
