Populist convert Santorum takes on Mitt's elites

After driving a pickup truck through all 99 counties of Iowa, Rick Santorum, a former member of the GOP leadership, has ended up firmly on the conservative Christian, populist side of the GOP’s cultural divide. Meanwhile, Mitt Romney, with his co-victory in Tuesday’s caucuses, can expect the cosmopolitan, business-friendly elite to rally behind him.

In a powerful victory speech that eclipsed Romney’s CEO-style pep-talk, Santorum on Tuesday night attributed his victory to “the same people that President Obama talked about who cling to their guns and their Bibles.” And Santorum added, “thank God they do.”
