How can anyone vote for someone who was proved to slander any American?

It's really easy actually, I'll walk you through the steps. You sign in at your local polling place (provided you're registered to vote), walk into the booth, check the box next to Barack Obama's name, turn in your slip of paper, get an "I Voted" sticker, and walk out with a sense of accomplishment and pride that you're working to make the country a better place.
