From the latest edition of the Suffolk University New Hampshire Primary tracking poll:
“For the fourth day in a row, Mitt Romney has fallen in overnight tracking, and Rick Santorum has dropped into fifth place among likely voters in the Jan. 10 New Hampshire Republican presidential primary, according to the latest Suffolk University/7News two-day tracking poll.
Ron Paul is gaining on Romney, while Jon Huntsman has rallied into third place.
Romney dropped 4 percentage points overnight to 35 percent. The former Massachusetts governor still holds a 15 point lead, but his margin has declined by 8 percentage points since last Tuesday, when 43 percent of likely Republican voters backed Romney."
