Gingrich hoping for an upset FLORENCE, S.C., Jan. 19 (UPI) -- Former U.S. House Speaker Newt Gingrich said he thinks he can pull off an upset in South Carolina's Republican presidential primary Saturday. Gingrich told The Washington Post in the few days remaining, he has to get votes away from rivals Rick Santorum and Rick Perry, who dropped out of the race Thursday, and "erode [former Massachusetts Gov. Mitt] Romney a little more." "I think we can do it," Gingrich said. In less than two weeks, the margin between Gingrich and Romney has shrunk by nearly half, to 10 points, in South Carolina. The Time-CNN poll was conducted before Monday night's GOP debate that Gingrich said was the best he's had all year. A win for Gingrich in South Carolina Saturday would sully the state's reputation as a killing field for political insurgents. In every GOP primary race in 32 years, South Carolina has voted for the establishment favorite and sent him on his way to the nomination.
