Former Sen. Rick Santorum (R-PA) announced Wednesday night that he will form an exploratory committee for the presidency in 2012, inching closer to declaring his candidacy.


"Now, the only test for me is whether we can raise the money that's necessary," Santorum told Fox News's Greta Van Susteren.

The Pennsylvania Republican has attempted to court social conservatives by making far-fetched arguments against abortion. And he has an awkward "Google problem" to overcome.
