I have a question

The entire McCain campaign is in high dungeon, bitching and whining about Wesley Clark’s non-questioning of McCain’s military service while at the same timing cavorting with the Swiftboat assholes that accused John Kerry of being a traitor in 2004 and whom McCain, at the time, denounced.

So my question is thus: where does Kerry find the restraint to not hunt down McCain and knock him the fuck out?
