NOT! I am unsure how much VP choices really matter for swinging states anymore, though it does not really help that recent candidates have chosen their VP for other reasons. The last president I think might actually have won a state because of his VP was Reagan in 1980. Even then, it is hard to argue TX really voted for him because of a CT carbetbagger who never managed more than a couple House elections. So we are back to JFK/LBJ (once again in TX, oddly.)

Of course, FL should actually be close, and is certainly critical now that it has the third most EVs, so putting Rubio on the ticket would be a smart move (and help Romneys credibility with the base.) It might even help seal the deal in AZ and put NM in play (it could be argued Rubio has little in common with Southwestern voters save religion and immigrant ancestors, but both are huge.) In that case Obama would be in truly dire straits, because Romney has to be the favorite in NH, and that would mean Obama could afford no more losses except IA—even WITH OH (sorry.) Looking at the map, it is hard to see why so many Dems are so cheery.
