Newt Gingrich, 2012 Republican Presidential Candidate | featured news

Rick Santorum has won the Mississippi GOP presidential primary, according to an Associated Press projection, following his earlier triumph in neighboring Alabama on Tuesday.

Rick Santorum seized the lead in the Alabama primary Tuesday night and edged ahead of Mitt Romney and Newt Gingrich in Mississippi, deeply conservative Southern crossroads in the struggle for the Republican presidential nomination.

Rick Santorum hopes to muscle Newt Gingrich out the race Tuesday and to force a face-off with Mitt Romney. But CNN's Candy Crowley reports Gingrich shows no signs of quitting.

Edward Morrissey says none of the candidates hit their targets for moving ahead on Super Tuesday, but hung on just enough to keep the crown out of Romney's reach

Mitt Romney apparently pulled off a narrow victory over Rick Santorum in Ohio on Super Tuesday. But Mr. Santorum scored victories elsewhere, competing with Mr. Romney’s achievement of collecting the most delegates and all but ensuring another round of intense infighting on the road to the Republican presidential nomination. Far from bringing new clarity to the race as some in the party had hoped, Tuesday’s results gave every candidate cause to keep driving forward —including Newt Gingrich, who won a definitive victory in Georgia. They also dashed Mr. Romney’s hope of using the night to assert himself as the inevitable nominee.

NBC News projects that Rick Santorum has won in Tennessee; Mitt Romney seen capturing Massachusetts, Vermont and Virginia while Newt Gingrich takes Georgia; Ohio is too close to call and Oklahoma is too early to call.

Newt Gingrich is taking his campaign's recent focus on reducing energy costs and boosting domestic production to the airwaves.
