Bloomberg as McCain's VP?

In his column today, Frank Rich reviews the misadventures of McCain's economic policy and speculates on Romney vs. Michael Bloomberg as McCain's VP pick. Not that I'm in the business of offering advice to the McCain camp, but I think Rich is right that Bloomberg would be a smart choice. McCain is desperate at this point; Intrade shows him with only a 30.5% shot at being the next president. He needs to do something to shake up the race, and picking Bloomberg would fit that bill.
