I’ll take a realistic stab at this.
Accepting certain truths:
1.) Mayors, Local Congressmen, Ambassadors aren’t going to get the nod.
2.) Certain people I like aren’t running (Jindal, DeMint, et al).
3.) Realistic choices are of Governors first, Senators second.
4.) Some folks have no chance in hell (Pawlenty).
Here is my list, based on those truths:
1.) Sarah Palin
2.) Haley Barbour (may or may not run, I say 50/50 right now)
3.) Rick Santorum (might be most radioactive of everyone, though)
4.) Newt Gingrich (Not the enemy some make him to be; very effective)
4.) Jim Thune (safe choice; not a likely nominee, though)
We’re so screwed...lol.
J/K
It’s got to be Sarah.
