Santorum?

Good guess but no sweater.

I guess that the one I have in mind won't get the nod because no one is remembering his name; that's not good.

(Still, he's a perfect former Senator to run and serve as Trump's Veep. Mature, but not too old.)

Bill Frist? I’m out of guesses lol

Were you thinking ol Fred Thompson? I supported him when he ran. Unfortunatly, Fred is dead (Nov 1, 2015)

and ... I thought you were referring to Marco because Marco is a future former Senator, since he is not running for reelection. I am amazed that Marco still has fanboys here on FR (not you, but in other comments that I read in this thread). With all the shrill against Ted ... Marco is 1000x worse than Ted, and there is nothing about him that is conservative.
