I predicted this; not here I don't think, but in another forum, before his surge, because Jupiter is in his sign. He is the only one among the candidates with lucky Jupiter now in their sun sign. But he will fade like all the others, after March if not before. He is the latest and probably the last "non-romney" Republican to emerge as the crazy right-wing's candidate. The GOP will settle for Romney, and Obama will defeat him.
Santorum is a reasonably honest and sincere candidate, with a sharp and reckless tongue, and consistently wrong on everything-- too conservative even for America. He is good at speaking to groups, but whether he has the skill to put together a good campaign we don't know yet. According to my crystal ball, he has no chance to win.
Good one, IK!
