Provisional ballots are counted 12 days after the election.
You may cast a provisional ballot if you run into the following situations at the polls.
Your name is not on the list. If you believe you're registered to vote, are at the correct polling place but your name does not appear on the voting list. You can ask the poll worker to contact the city or town hall to confirm your registration. If your registration is not verifiable, you may cast a provisional ballot.
Incorrect party enrollment. If you are voting in a party primary and believe that your party enrollment is incorrect as listed, you can vote a provisional ballot for the party you believe you are registered with.
Unable to provide ID. If you are not able to provide the proper ID, you may cast a provisional ballot. Your ballot will not be counted until you return with ID to the polling place or the office of your local election official by the close of polls.
