A new South Carolina poll shows North Carolina Sen. John Edwards (search) leading the race for the Democratic presidential primary there with the Rev. Al Sharpton (search) not far behind.

The Feldman Group Inc. (search)'s poll of 400 likely voters for the primary showed Edwards with 17 percent and Sharpton with 12 percent. Twenty-two percent of those polled were undecided.

The telephone poll was conducted Nov. 20-23 for Greenville Magazine and had a sampling margin of error of 4 percentage points.

The new poll comes four weeks after an American Research Group (search) survey showed retired Gen. Clark leading with 17 percent to Edwards' 10 percent. More than a third of that poll's respondents were undecided.

Clark had 10 percent in the Feldman Group Poll, in which 49 percent of the respondents were black, Feldman Group President Diane Feldman said. Democrats here expect blacks to account for about half of the primary voters.

Sharpton, who is black, led among black voters; Edwards, who is white, was second with that group, Feldman said.

The rest of the field: Former Vermont Gov. Dean had 11 percent, Sen. Joe Lieberman of Connecticut 9 percent, Rep. Dick Gephardt of Missouri 8 percent, former U.S. Ambassador and Sen. Carol Moseley Braun of Illinois 6 percent, Sen. Kerry of Massachusetts 5 percent and Rep. Dennis Kucinich of Ohio 1 percent.
