A reminder from the League's Voter Registration team:
Did you request a mail ballot and now want to vote in person? That's fine. You'll need to bring that mail ballot/envelopes into the polling place and surrender it to an election judge. Once you do that, you'll be able to vote in person that day.
If you're not able to bring in the mail ballot you received, you'll still be able to vote in person, but it will be provisionally. That means the County Clerk's office will hold your ballot for 14 days after election day before your votes are counted.
