Bo or Carrie?

So Carrie Underwood is the new American Idol, good for her. I'm surprised no one objected to Bo singing the mildly racist "Sweet Home Alabama" for his closing number, but whatever, he was building up all season for that song. One interesting piece of trivia came from the president of the company that ran the voting (what was his name?): there were more than 500 million votes cast over course of the season. I wonder if that many votes have ever been cast over any one issue in the history of civilization? I'd bet not.
