For information on where to vote:
If you or anyone you know has questions or trouble with voting, call the hotline at 1-866-OUR-VOTE.
It's a nonpartisan group of trained volunteers with access to information about voting (including the laws) in all 50 states. They are there to help people get access to the polls and to document and counteract voter suppression. They can tell you things like when the polls are open, what kind of ID you need (if any), what to do if you recently moved, etc. They can also usually check your voter registration and tell you your assigned precinct number and location.
