You wrote a very logical post...however, you make an assumption that McCain will behave as a conservative/Repub. I don’t think he will. He will move left. McCain really likes the Dems and all the things you fear will happen under McCain. The GOP can not be expected to fight their own President...The GOP would fight Obama or Clinton.
If McCain was a normal moderate like say Guliani, I would vote for him because everything you say would be true...better than Obama etc. However, this is McCain who has furthered his career stabbing Repubs in the back. Thus your argument fails when one considers McCain’s true character.
Not when it comes to the defense of our nation.

Plenty of Repubs have fought against GWB. Thus, your argument fails.
That is really the point, isn't it? He is a traitorous bastard. He has no honor. How can he be trusted at all?
