One thing that Kerry has done that damaged his chances is the fact that he blatantly lies about things he knows nothing about.
Nobody believes he's a farmer. Nobody believes he's a hunter. Nobody believes he knows anything about sports. The fact that he repeats the same old lie that Bush lied about Iraq proves him to be a liar.
Now the swift vets have come out and caused a lot of people to question his credibility on that front as well.
At least not team sports, as Peter Gammons revealed, and as rugged as he looks in his publicity photos, we know now that he throws like a girl.
