Still, Santorum has gained heavily in the last week, climbing 15 points as Gingrich has fallen by six and Romney by nine.

All of the candidates have negative favorability ratings in Georgia, although the state is still solidly in the Republican corner for the general election this fall.

Georgia is one of 10 states to vote in the March 6 Super Tuesday primaries.

Oklahoma, Alaska, Idaho, Massachusetts, North Dakota, Ohio, Tennessee, Vermont and Virginia will also vote next week.

Gingrich is not competitive in the Michigan or Arizona, which will vote on Tuesday, and so abandoned his efforts in those states to concentrate on the Deep South, where he is staking his campaign.

The former House Speaker was in Tennessee on Tuesday.
