You're probably registered to vote. But if you aren't, use this little widget to get started, or share it with a friend, a fresh 18 year old, a new neighbor.
Remember, you can't vote if you aren't registered. Do it soon, because the deadline in some states is as soon as October 6. (And don't give me any grief about the fact that the widget is from the Obama campaign. You can use it even if you want to vote for the other guy.)
