A new poll done for NBC in Iowa has John Edwards continuing to lead, with 30% of likely Democratic caucus voters backing him. Hillary Clinton (D-NY) is second at 21%, with Barack Obama (D-IL) just behind at 18%.
Edwards, who has been finishing third and well back in most national polls, has to be gratified with the results, but has to worry, too, that his Iowa backers are hearing about those surveys and will begin to believe that he can't win. Clinton, meanwhile, should be concerned that she's only slightly ahead of Obama.
Should Edwards' support dip in Iowa, who would pick up more of his voters, Clinton or Obama? My bet is on the Senator from the Land of Lincoln. (Remember, he's a neighbor from just across the Mississippi; that won't hurt him in Iowa.)
