There is a website that you can use to ensure that your voter registration information is complete and accurate. Don't wait until the November 4th to check. Make sure your vote goes through without a hitch.
Go HERE, The National Association of Secretaries of State, and select your state. Many states have changed their requirements for this election, you may need additional identification, or proof of residence, or you may need to hop on one foot and pat your tummy. Click through to your state and check to see that you are registered and that the information is accurate. Check to make sure that you know where you're supposed to go when you vote and what the hours are.

Even more voting day tips: if your right to vote is challenged, do not accept a provisional ballot which deposits your name at the bottom of a very long list of problem ballots. Instead, demand adjudication from the poll judges, who are always present in each voting location.
This means you have the right to stand there until a decision is made about your status—but it also wouldn’t hurt to carry this phone number to help yourself or others around you: 1-866-OUR-VOTE.
I've heard of situations where someone's address didn't match on their registration and their ballot was put in a pile. I'm guessing it was "the pile to nowhere". Make sure your vote gets counted!!!
