New poll: Brown up 9

A new InsiderAdvantage poll conducted exclusively for POLITICO shows Republican Scott Brown holding a 9-point advantage over Martha Coakley a day before Massachusetts voters trek to the ballot box to choose a new senator.

According to the survey conducted Sunday evening by the non-partisan firm, Brown leads the Democratic attorney general 52 percent to 43 percent.

The results came as Suffolk University in Boston released a survey Monday reporting that Brown surged to a double-digit lead in three Massachusetts communities identified as bellwethers because party registration in those cities is similar to the statewide voter makeup and because in the most recent “like election” – the November 2006 Senate race– the results in all three communities were within 1 percentage point of the actual statewide results for each candidate.

"I actually think the bottom is falling out," said InsiderAdvantage CEO Matt Towery, referring to Coakley's fall in the polls over the last ten days. "I think that this candidate is in freefall. Clearly this race is imploding for her."

The numbers show males and independents overwhelmingly breaking for Brown, who has married his GQ looks with a populist tone in a pick-up truck on the campaign trail.

Brown holds a 15-point lead among males and crushes Coakley by 41 points among self-described independents, a group that's been steadily inching away from the Democratic party over the last year due to growing apprehension with government spending, bailouts and health care reform.

"Men are not going to vote for Coakley at all. You have a very angry male voter who's repudiating whatever is being said in Washington and they're taking it out on this woman. And independents are clearly going to the Republican in droves. What's left are the Democratic voters," said Towery, who is a former aide to Newt Gingrich.

And the survey shows almost a quarter of Democratic voters lining up with Brown.
