HHMMmmmmm........ Time will tell, but either way, If either Romney or Santos wins, Obama is eagerly awaiting either one. (especially Santorum) Newt would have been formidable and Obama knows it. Unless things turn around and they still can, we are not looking very good.
Santorum may win, and in the unlikely event he wins the White House, you can guarantee he will be a Social Conservative, Christian based leader, very much like George W. Bush. Fiscally, very much the same in that department also.
Your memory is short. Santorum was a major player in the welfare reform act which was a game changer for a while.
