Why so many on the Right detest McCain ought not be that tough a mystery to crack - they're returning the bile he's spewed in our direction for years.
McCain argues against tax cuts using "class warfare" rhetoric.
McCain gives Democrats cover for accusing the Bush Administration of "torture" with his very public posturing about waterboarding (this after we all know waterboarding broke KSM, by the way).
McCain tries to ram his immigration bill through over conservative objections & associates himself with that lil' puke Graham, who calls us bigots.
McCain snatches defeat from the jaws of victory with his "Gang of 14" deal. (It broke the logjam for a select few - Bush nominees are still being stalled - and took an issue where we had the high ground off the table.)
McCain provides cover for Democrats on "McCain / Feingold" - if he doesn't know Democrats will use it as a political weapon against Republicans when they get the chance, if he can't recognize how it enhances the influence of a media hostile to our interests, he's a fool.
McCain's harshest rhetoric, etc. is directed at "other" Republicans - find me criticism of Kennedy, Feingold, Edwards, Clinton, Gore, etc. that matches the temper & tone of what he's said about Romney on Iraq.
McCain's no party builder. He has no respect for anyone on "our side" who doesn't agree with him (it's almost as if he gives Democrats a pass because they're in the "other army"). He grandstands constantly.
McCain v. Hillary or Obama is a tough vote for me. I don't know how it comes out - - - - as the day draws nearer, I suppose I'll think a lot about just how much damage I think the Democrat could do. Maybe it'll be enough to convince me to fill in the "McCain / _______" bubble on the ballot.
But make no mistake - if that happens, it won't be a vote "for" McCain.
But as the Anchoress says, much could happen in the interim, so we can afford to chill a bit and wait.
THEN we can go ape.
