2012 redux potential running mates?

I’ve made a list so far of some potential running mates for a hypothetical 2012 Redux off the top of my head, so far being:

⭑ Representative Paul Ryan from Wisconsin (OTL)
• Representative Mike Pence from Indiana

• Governor Chris Christie of New Jersey
• Governor Bob McDonnell of Virginia
• Governor Mitch Daniels of Indiana

• Senator Marco Rubio from Florida
• Senator Rob Portman from Ohio
• Senator Kay Bailey Hutchison from Texas

• CIA director David Petraeus

Does anyone else have any other ideas?
