http://news.bostonherald.com/national/national.bg?articleid=596 By David R. Guarino and Andrew Miga/ BREAKING NEWS Sen. John F. Kerry has catapulted into a 10-point New Hampshire lead six days before the nation's first primary, bouncing out of Iowa and over longtime frontrunner Howard Dean, according to a new Boston Herald poll. _____The Massachusetts senator leads Dean 31 percent to 21 percent, with a slipping Wesley K. Clark at 16 percent after skipping the Iowa caucuses. _____Sen. John Edwards is in fourth place with 11 percent, followed by Sen. Joseph Lieberman with 4 percent. Rev. Al Sharpton and Rep. Dennis Kucinich continue to barely register. _____Herald pollster R. Kelly Myers called it a ``dramatic turn-around for John Kerry.'' _____``His once fledgling campaign has found new legs and he now finds himself the clear front-runner in this race,'' Myers said. _____The poll, of 501 likely Democratic primary voters, was taken by RKM Research and Communication Tuesday and yesterday in the immediate aftermath of Kerry's surprise Iowa caucus victory. The poll's margin of error is plus or minus 4.4 percent. _____The Herald poll is the first two-day sampling since Iowa's vote.
