I believe the debates will just reaffirm one's choice of President. The one's who support Romney will say he won and the one's who support Obama will say he won.
Much like your choice of which news broadcast you watch CNN or Fox it just confirm your position of being " correct".
The debates are really for the undecided the truly undecided and therefore important in a close election.
Romney's task will be to erase the impression that he is a clue-less rich guy, a heartless hard line guy, and Obama will have to erase the impression as incompetent leader, a socialist at heart, that wants to fundamentally change America to a socialist country.
Both will have to show their cards on how to get America's economy going at some reasonable rate.
But under debate rules they have to do so in under two minutes which is ridiculous.
If we choose the most important position in America under this format shame on us!
