Reports of the incident seem to vary an awful lot, so I'm not sure how accurate they are. Some would say this is a reflection of the Obama adulation in much of the press. I think it might well be an Obama supporter making it seem bigger than it really was.
However, both Bill and Hillary have a long reputation for this sort of thing...as does McCain. That might lead one to believe that to be a passionate leader, you have to be...passionate, I guess.
