Obama: “Like Any Politician at This Level, I’ve Got a Healthy Ego”

The Democrat expresses confidence, says he's been buoyed by the size of the crowds greeting him at his final stops before Election Day in an interview with USA Today.

Says his biggest worry for Tuesday is "complacency," meaning people won't go to the polls because they think he's already got it in the bag.

Also boasts about his campaign's organization over McCain's. "I'm able to bring a lot of smart people together and get them to cooperate instead of engaging in a lot of infighting."
