A Romney/Romney from ten years ago ticket would be superlame
But if the 2002 Romney was a veep choice, he'd also be unacceptable
2002 Thune would be okay though, he was a fairly decent Congressman but turned out to be a dud in the Senate.
Hey, as long as we're on this, can I bring back the 1998 Bob Barr forward in a time machine so he can beat the crap out of his 2012 counterpart? ("Look, just shut up, you ACLU whore!") I'd pay money to see that. ;-)
