New IA, NH and SC '08 polling

These polls came in just hours ago.  Edwards maintains a lead in Iowa, while New Hampshire and South Carolina, as of now, are still in the Clinton column (conducted 4/27 through 4/30 among likely Democratic primary voters):

IOWA
John Edwards - 27%
Hillary Clinton - 23%
Barack Obama - 19%

NEW HAMPSHIRE
Hillary Clinton - 37%
John Edwards - 26%
Barack Obama - 14%

SOUTH CAROLINA
Hillary Clinton - 36%
Barack Obama - 24%
John Edwards - 18%

Take your pick: Clinton, Edwards or Obama?  Unless Gore enters the race, it will be those three candidates from here on out.  Neither Bill Richardson nor Chris Dodd helped themselves out in last week's debate, and their campaigns appear to have hit a rock.  As for Biden, although he did exceed expectations in the debate, his lack of fundraising will make it nearly impossible for him to compete by the time September and October roll around.
