I am going to vote tomorrow.
You should too.
I'm reposting the links below from this article by s.e. smith, which contains even more resources and suggestions than those listed here.
Here is information on how to find your polling place, when it's open and what kind of ID you will need. You can also refresh your knowledge of your local candidates, which I'm going to do tonight.
Here, from Election Protection, is a list of polling place changes due to Hurricane Sandy. If there is a problem with voter intimidation at your polling place, you can and should call this organization at 1-866-OUR-VOTE to report the problem and get suggestions for action.
Bring your camera and/or your phone, because you can also document voter intimidation (of you or someone else) directly at Video the Vote.
Here is the ACLU's state-by-state guide to voting rights.
Don't forget to vote on your states' ballot measures as well!
I will be voting for the candidates that come closer than any of their opponents to civil, public service: plans and policies that either serve everyone equally or provide more to people who have less; liberties and opportunities that really are for everyone; efforts to, at least, prevent the abuse of existing power, and at best to to even out the distribution of future power. I hope you will do the same.
