I think you are admitting he didn't: I would have been screaming in self-defense if I were President Bush, but that's not what he thought was the right thing to do.
I mean, how is one to respond to a play or book calling for your assassination? The rhetoric was far worse.
Oh.......and campaigning against Bush was only one reason McCain lost. Certainly not the only reason.
He was a horrible candidate. NO disagreement there.
