Ideological soul-mates, that's for sure. Some other folks who could potentially be on McCain's short list:

I like Martinez -- I think he gets a bum rap -- but obviously some immigration folks aren't crazy about him.
Mel Martinez can never be VP. He was born in Cuba.
I don't care who he picks either since I wouldn't vote for him if he put me on the ticket, but since he's not interested in geographical balance, doesn't seem to think he needs southern states, and is hunting for a clone, maybe his shadow Chuck Hagel would do. Unless Hagel has a better offer from Bloomy.
We need one page of these that are fronts and, one page of these for the backs, that we can print and cut, to fill the prepaid envelopes from the RNC and the ACU.There will be a price to pay for supporting McCain.
We can vote conservative on Senate and House primary seats, and vote for anyone other than McCain on the Presidential seat, including a democrat in the general election.
