Negative campaigning works. Presidential candidates cannot win without them.
I know that all sides do it. Today we're seeing an odd contrast though... Obama is talking about positive change. mccain, his campaign people, FOX news, and all the fox commentators, are all doing some negative obama bashing (much of it valid, but much of it about 'why won't obama acknowledge this or that).
mccain has more experience, was right on the war, and is the wiser man. He's just losing his shine from 2000, and turning into a pissy, bitter guy. He can't do that and expect to win.
