One year ago I would have envisioned Jim Demint rising to the top on a tea party ticket
November 2012 Headlines: Newt/Sarah ticket WINS! Obama fraud trial starts with jury selection.

There's another name to add to the list of possible Romney running mates: Santorum, Pawlenty, Ryan, Rubio, DeMint. (If Cain can weather the storm, maybe add him to the list.)
Again, this is prediction, not preference.
