Edwards Continues Climb in Carolina

From TPM

The new Zogby poll in South Carolina shows Barack Obama continuing to hold a healthy lead over the rest of the field — and that John Edwards just might be sneaking up on Hillary Clinton for second place. Barack Obama leads with 38% support, followed by Clinton at 25%, and Edwards with 21%.

Some commentary from John Zogby: "The real movement here is by John Edwards, who is the only one who continues to gain ground in our three-day tracking poll ... Can he catch Clinton by Saturday’s vote, perhaps bumping her from a second-place finish? Perhaps that is why she has returned to the state to campaign."
