Santorum on the campaign run - backward

CAN ANYONE EXPLAIN - in rational terms - what Rick Santorum is doing in his possible candidacy for the presidency? His message casts him as a Republican super-hawk, super-patriot, super-family man, super-holiness and super-critic of the man in the Oval Office. He is also the super-wholesome fellow who lost his U.S. Senate seat in 2006 by 18 percentage points after Pennsylvania voters grew tired of his haloed gibberish. His latest assaults on Barack Obama accuses the president of not liking America and being totally adrift in foreign policy. He's also berating Planned Parenthood for practicing "racial eugenics". ( So much of the blather on the political right is inspired by racism, don't you think?) He will be going to New Hampshire again and again to make his case up there - and maybe lose it in the same breath. What makes him do it against such impossible odds? As my uncle George used to respond to my silly childhood questions, "Damned if I know."
