McCain's Veep Dilemma

A reader writes:

I agree with everything your reader said on Romney but ... Biden would CHEW Pawlenty up, vomit him, make mincemeat of him and rechew him up. Which is why people are right when they say McCain is boxed in with his VP pick.

For whatever flaws Obama's choices had, none of the choices of McCain make sense. Lieberman's downsides are obvious. Meg Whitman would be smart politics but completely deprive him of the whole "inexperience" thing that is clearly at the core of his "official message" against Obama. Romney is a catastrophe. Pawlenty is a pathetic lightweight. Interestingly, Huckabee does seem like someone who makes sense (in a way that kind of crazy makes sense for a Republican) and sure enough, Ambinder says he is the one Obama people fears. But we know he is - like a certain lady - saving himself for 2012 and is not being vetted - or is he?

McCain-Huckabee? Is Pawlenty that reminiscent of Quayle?
