Early Voting + Absentee Voting

Early Voting Dates: None

To vote absentee by mail, first you’ll need to apply for an absentee ballot (click here) no later than April 27th. Then, when you complete your absentee ballot, it must be mailed in time to be received by your town clerk on election day.  We recommend mailing at least 10 days prior to election day from an out-of-state location, or 5 days prior to the election from an in-state location.

Or you may return the ballot in-person to your town clerk or polling place by the close of polls on April 28th.

You’ll need to give an excuse to vote by absentee ballot. Info here on what qualifies.

If you are applying for an absentee ballot within 6 days of the election, this is considered and emergency absentee ballot.  There are additional requirements for your excuse.  Info here on what qualifies.
