These notes came from an e-mail sent out by the Obama campaign to supporters:

If you are in line or in the process of voting at 7:00 p.m., the polls must remain open until you have an opportunity to vote.

If your name is not in the voter registration book, you still have the right to vote by using a provisional ballot. If this happens to you, you should ask the poll worker for a provisional ballot.

If you have moved within the same precinct, you have the right to vote at that precinct.

If anyone challenges your right to vote, you have the right to vote by provisional ballot.
