You might be able to vote in person on Election Day, even if you received a mail-in ballot. Every state has different rules, so check with your state or local election office for the specific procedures. Typically:
You’ll take your absentee ballot to your designated polling place on Election Day. Your polling place may change, especially during the coronavirus pandemic. Check your polling place’s location before you go.
Depending on your state's rules, you might exchange your un-cast absentee ballot for an in-person ballot, or complete your absentee ballot and hand it in, or cast a provisional ballot.
If you forget to bring your absentee ballot with you, you may be able to cast a provisional ballot. Provisional ballots are counted once your election officials verify your voter status.
It is always good to check with your local election office prior to making your final decision.
