Check this out from Newsweek:

Riding high on his victory in the Iowa caucus—and benefiting from former Vermont governor Howard Dean’s embarrassing “I have a scream” speech—Massachusetts Sen. John Kerry has surged to the head of the pack of democratic presidential hopefuls, according to the latest NEWSWEEK poll, commanding 30 percent of support from registered Democrats, up from 11 percent two weeks ago. And for the first time in the poll's history a Democrat is enjoying a marginal advantage over President George W. Bush. In a hypothetical face-off, Kerry commanded a three-point lead over the president. Dean’s support among registered and likely Democrats, meanwhile, has been cut in half, to 12 percent. That puts him in three-way tie for second place in the Jan. 27 New Hampshire primary with retired Gen. Wesley Clark (12 percent) and North Carolina Sen. John Edwards (13 percent). [emphasis our's.]
