Romney and Santorum See Bounce in South Carolina Poll January 6, 2012, 1:32 pm Now that Iowa's caucus is over, the candidates" standings are rolling in from the next set of states in the primary lineup. And more poll results are expected before the day is over. The latest news comes from South Carolina. Mitt Romney's support among those in the Republican establishment includes Gov. Nikki R. Haley of South Carolina, who has endorsed him for that state's contest on Jan. 21. And now the latest poll of likely Republican voters there suggests they, too, are starting to rally around Mr. Romney. Mr. Romney, who stepped into the state briefly this week after his close victory in the Iowa caucuses, is backed by 37 percent in a CNN/Time/ORC International poll. That's up from 20 percent in the same poll released early December. Rick Santorum, the former Pennsylvania senator, also appears to have benefited from his near-tie with Mr. Romney, the former Massachusetts governor, in Iowa: his support jumped to 19 percent from 4 percent. As in Iowa and nationally, Newt Gingrich's numbers are plummeting. In December, the former House speaker was backed by 43 percent of likely voters in South Carolina. Now, less than half as many - 18 percent - said if the primary were held today, they would vote for him. In the latest survey, twice as many likely voters chose Ron Paul: he is at 12 percent, up from 6 percent. Rick Perry is backed by 5 percent and Jon M. Huntsman Jr. by 1 percent. But the candidates" standings are in flux. Almost half say they could change their minds within the next two weeks. The telephone poll was conducted Wednesday and Thursday with 485 registered voters identified as being likely to vote in the South Carolina Republican primary. The margin of sampling error is plus or minus 4 percentage points.
