We’ll update when we get the full results.

UPDATE: Here are the full results:

Nearly one-in-three primary voters (31%) in South Carolina say they still could change their minds, and it’s unclear how Perry’s withdrawal, the growing dispute over Romney’s taxes or an interview this evening with one of Gingrich’s former wives might impact the contest. Six percent (6%) still haven’t made a choice yet. Sixty-two percent (62%) now are certain of how they will vote on Saturday, including nearly 70% of those supporting Gingrich, Romney, Santorum and Paul. Just 37% of Perry voters have made up their minds at this point.
Gingrich holds a two-to-one lead over Romney among both Very Conservative and Tea Party Republicans in the state. The former Massachusetts governor holds a far more modest lead among Somewhat Conservative voters and those who are not members of the grassroots movement.
Evangelical Christians prefer Gingrich by 37% to 21% margin, with Paul and Santorum at 16% and 15% respectively. Romney leads among all other religious groups.
Despite continuing criticism of Romney’s record as a businessman, 62% of all South Carolina primary voters now feel his business record is primarily a reason to vote for him, while just 22% view it as chiefly a reason to vote against him. Sixteen percent (16%) are not sure.
By a narrow 36% to 31%, primary voters think Romney would do a better job than Gingrich managing the economy. Seventeen percent (17%) feel Paul would do a better job.
