If you're in line on election day at 7 PM, the poll officials are required to let you vote. After 7 PM, you will not be allowed to vote. Same rule applies to Advanced In Person (aka Early Voting).

However, if you're not in your assigned precinct, things change. Before 5 PM, you'll be directed to go to your assigned precinct, and we will provide you with that address. After 5 PM, you'll be allowed to vote using a provisional out of precinct ballot (OP). A provisional ballot will probably have to be cured (I don't have the instruction letter in front of me), requiring a trip to Elections headquarters. Thankfully there's only one race, so an OP ballot will be identical at any precinct.

Also, if you did not vote on November 8, you can vote on December 6, as long as you're a registered voter.
