I think these also-rans like Santorum, Rick Perry, Huck, Jim Gilmore, and George Pataki are running for president to raise their public profile. They know they have no shot in hell of winning the presidency, but they want to look and sound good in front of the cameras for a debate or two in hopes of catching attention from a corporation or some other organization to get their next high paying gig. It’s simply resume enhancement at a high level.
Exactly how I feel!
Huckabee had a high paying gig. He really did or does think he has a shot.
