Rock The Vote
Rock The Vote is your one-stop shop for everything you need to know about voting - not only can the site help you find your polling place, it also tells you what your voting rights are as a U.S. citizen and how to contact your elected officials. If you're ready to engage in issues important to you and your community hard-core, you can even sign up to volunteer at an event near you.
