GOP race heats up in the South

The G.O.P.  race continues to heat up, but now it's shifting to the south.

While Mitt Romney and Rich Santorum continue to battle, they both think they have the edge in the southern states.

Mississippi and Alabama are the new targets for these candidates.

Rick Santorum said, "People of Mississippi and Alabama want a conservative, for sure."

Mitt Romney added, "This could be an election that comes down to a very small margin between the
 three people running here most aggressively"

The primaries take place in Alabama and Mississippi on Tuesday.
