In the the aftermath of this week's presidential debates in New Hampshire, Clinton and Romney come out on top in a new Mason-Dixon poll of likely primary voters there. Among likely Democratic primary voters, Clinton leads Obama, 26%-21%, with Edwards at 18%, Richardson at 9%, and Biden at 6%; no other Democratic presidential contender gets more than 1%.
Among likely GOP primary voters, Romney leads McCain, 27%-16%, followed by Giuliani at 15%, Fred Thompson at 12%, and Huckabee at 5%.
The Mason-Dixon poll -- which was given exclusively to NBC and MSNBC -- was taken June 4-7, 2007, and the Dem field has a margin of error of +/- 4.9%, and the GOP field has a margin of error of +/- 5.3%.
