An American Research Group poll released Friday night showed Mike Huckabee ahead of John McCain by 33 percent to 26 percent with Fred Thompson at 21 percent, and Mitt Romney at 9 percent. The margin of error is 4 percent. This poll is at odds with a Jan. 16-17 poll we reported earlier by Fox News poll showing McCain in the lead.

On the Democratic side, Barack Obama leads Hillary Clinton 45 percent to 39 percent with John Edwards at 10 percent. Margin of error here is also 4 percent.

Another poll, by SurveyUSA conducted for South Carolina news outlets, had McCain ahead of Huckabee 31 percent to 27 percent. But the poll said the difference was within the margin of error and either could win.
