Earlier today, I offered the comment in a Facebook post:
Too bad Chris Christie can't be named VP, help Romney win, then resign, with Rob Portman being named Vice President so that Christie can return to be New Jersey's Governor--I mean, what is Christie going to do that's more valuable than being Governor after the ticket wins? Is there some way of Constitutionally giving enough "add-on" duties to the VP to make being VP, as opposed to running for VP, sufficiently valuable?
No one I've spoken, Tweeted, or written to seems to know the answer to this last question. I don't believe the President's Cabinet (or, at least some of its newer positions) are creations of the Constitution, so, for example, would it be Constitutional for a VP Rubio to be Secretary of State, or a VP Ryan or Daniels to lead the Office of Management and Budget? What's possible, both to entice the Ryans, Rubios, etc. to accept a nomination and be valuable if/when they win, and what "add-on" duties would suit the various people we keep talking about? Calling Profs. Epstein and Yoo and everyone else...
Bonus sub-question: in 2012, how much clout does being VP carry, as compared to simply being a "mere mortal" surrogate put into "heavy rotation"? In other words, does Sen. Rubio campaigning in Florida really have less pull than VP nominee Rubio?
