Romney wouldn't. Huckabee wouldn't. Do you think Palin or Gingrich are going to beat Obama? Just asking
And Obama is no Jimmy Carter.
Of the people you just mentioned Romney is probably the only one with a chance of winning the nomination.
Just because the media gives Hubabee and Palin all the attention that doesn't mean either of them are even going to run. Palin has shown no sign at all of setting herself up for a run, I think she realized that she wouldn't have a chance at this point.
The most likely Republican nominees are Romney, Haley Barbour or Pawlenty.
Expect one of them to use the old Reagan line "are you better off today than you were four years ago?"
How does Obama respond to that question?
