Newt Gingrich is sticking in the race, despite a disappointing second-place finish in Alabama and Mississippi. The GOP campaign is essentially a two-man race between Mitt Romney and Rick Santorum, with Gingrich representing a potential drag on Santorum. But the former speaker doesn’t see it that way. After last night’s results came in, he gave a speech that seemed to suggest he and Santorum could work as a team to prevent Romney from winning the nomination. “Between Santorum and myself, we’ll get over two thirds of the delegates and the so-called frontrunner will get less than a third,” Gingrich said, which could force a contested convention.
