Why not just call it treason?

Well, it finally happened. The Right Wing Media has called for John Kerry's arrest. I thought that they would just call him a traitor for trying to "overthrow the government" as an act of treason. I'm surprised that they actually based this on a factual statement from John Kerry, at least factual in that Kerry actually said it. Usually they just make stuff up, like all that crap that "Al Qaeda wants Kerry to win" and "If you elect Kerry, you will get killed by terrorists, and it will be your fault!"Wh
