GOP hopefuls look South
WASHINGTON - Polls show a close race in the two Republican presidential primaries set for Tuesday. Alabama and Mississippi are seen as critical to Newt Gingrich's ability to stay in the race. A Gingrich aide has said the former House Speaker must win both primaries. Rick Santorum is looking to emerge as Mitt Romney's sole conservative challenger. Santorum said he didn't ask Gingrich to get into the race and he won't ask him to get out either. Romney is seeking a Southern breakthough to show he can win the support of evangelical voters. Romney and Santorum each won a caucus state Saturday; Santorum in Kansas and Romney in Wyoming.
