I know many FReepers like Rick Santorum but he has one of the same problems as Romney, he’s not inspiring.
However there also is one thing he doesn’t share with Romney and that is he doesn’t have GOP Establishment backing.
That is something Santorum shares with Gingrich (but since he’s not a threat to Mitt he’s not being reamed).
The one thing Gingrich does have that Mitt and Rick don’t have is his ability to inspire and teach, and that makes him the anti-Romney candidate for conservatives.
