Neither will, Hillary is too unpopular outside of the Democratic beltway. Al Gore is more popular than Hillary. McCain while having certain Conservative creditials is too much of a maverick to be controlled by the far right wing, same goes for Rudy. Also his brown-nosing of Bush last election put many moderates off their lunch.
It will be outsiders on both sides.
