Voter Information Tool by Google
https://www.google.com/elections/ed/us/vote

Google Official Blog: “Every four years in the United States, people prepare to head to the polls and increasingly search for information about how to register to vote, where to vote and who is on their ballot. Even though it is 2012, important voting information is disorganized and hard to find on the Internet. To help voters research candidates and successfully cast their ballot on Election Day, we’ve launched our new Voter Information Tool. You can enter your address to find information on your polling place, early vote locations, ballot information with links to candidates’ social media sites and voting rules and requirements.”
