Newt Gingrich says he's not dropping out, despite increasingly loud calls from Rick Santorum supporters for him to do so. "If I thought [Santorum] was a slam dunk to beat Romney and to beat Obama, I would really consider getting out," Gingrich said in a radio interview today. "I don't." He pointed out that as of Nevada, some were calling for Santorum to drop out. "He ignored all those. He now has had a terrific month. "
Gingrich is now focused on Alabama and Mississippi, the Atlanta Journal-Constitution reports, in his mission to sweep the South. "Spartanburg [SC] all the way to Texas, they all need to go for Gingrich," a spokesman admitted. Santorum's supporters, meanwhile, insist that Gingrich's lackluster Super Tuesday showing—he came in third or worse everywhere except Georgia—should knock him out. "Newt has become a hindrance to a conservative alternative," a Santorum PAC adviser tells Fox News, arguing that without him, Santorum would have won Ohio and Michigan.
