I wonder if Santorum will develop the financial capabilites to stay in it. I certainly believe Romney will focus his machine on Santorum. Romney doesn't consider Paul a realistic threat but perhaps he'll fear Santorum as someone who can steal the nomination through social conservatives. Also Santorum is gonna have people dig up his record but I wonder how Romney would attack Santorum given his own past.
F.Y.I. Appearantly it was a tie. Santorum, Romney, and Paul all earned the same amount of delegates (7) even though Santorum and Romney got 4% more each then Paul in terms of voters.
