Sen. Jeanne Shaheen (D-N.H.) would have an 8-point lead in a match-up against former Sen. Scott Brown (R-Mass.) this fall, according to a poll released Friday by the Democratic firm Public Policy Polling.
The survey, conducted on behalf of the League of Conservation Voters, found Shaheen taking 47 percent to Brown's 39 percent -- the third poll in a row to show her with a clear edge over him. A WMUR/University of New Hampshire poll gave Shaheen a 10-point advantage, while a survey from the Republican firm Harper Polling found her 5 points ahead.
Although Shaheen has held an advantage in nearly all polling released since 2013, two January surveys had found the race either narrower or tied.
HuffPost Pollster's average, which includes all publicly available polling, gives Shaheen a lead of just under 9 points.
The League of Conservation Voters earlier this month announced a $200,000-plus TV ad buy targeting Brown.
The former senator is reportedly serious about laying the groundwork for a possible candidacy, although he has yet to announce whether he's running. Brown told Fox News on Thursday, "I'm going to make some decisions and we'll see what happens." New Hampshire's filing deadline is in June.
The PPP poll used automated phone calls to survey 1,354 New Hampshire voters between Feb. 19 and Feb. 20.
