Is Obama Ready to be President?

Newsweek poll show Hillary with a 12 point lead on the question of readiness. Can Obama respond to attacks without abandoning the High Road he established as the foundation of his campaign? Can he demonstrate his readiness to lead by winning big states that Democrats have to win to secure the White House, or is it enough for him to win "red" states that Democrats have no recent history of carrying. Also, what about the persistent questions about his association with Rezko, Auchi, Ayers and others?
