It's a mystery MORE and GOP Sen. Scott Brown locked in a dead heat in their contest for Senate in Massachusetts, with Brown's efforts to convince voters he is a centrist Republican resonating with voters.

A Boston Globe poll released Sunday shows Brown with 37 percent support from likely voters to Warren's 35 percent. Brown's two-point edge falls within the poll's 4 percent margin of error, however.

But the race is still fluid months ahead of their November match-up, with over a quarter of those surveyed, 26 percent, saying they remain undecided.

The poll also finds Brown, the only Republican lawmaker in the state's congressional delegation, popular with voters. Fifty-four percent surveyed viewed him favorably, with 29 percent unfavorable.

Head to head, 57 percent said Brown was a more likable candidate than Warren, at 23 percent. A plurality of Democrats also pegged Brown as the more likable candidate. 

Brown's efforts to paint himself as a bipartisan lawmaker also appear to be paying off, with 49 percent saying he would work better with lawmakers across the aisle, compared to 27 percent for Warren.

Forty-four percent said Brown was influenced by the Republican Party, while 27 percent said he votes independently.

Brown won the Senate seat long held by the late Sen. Edward Kennedy (D) in a 2010 special election. But to hold his seat in the deeply blue state, he has worked to paint himself as willing to reach across the aisle and work with Democrats.

The poll finds Warren is boosted by her work as a longtime consumer advocate, with 44 percent to 35 percent saying she would do more to help blue-collar voters.

Warren still faces a Democratic primary, but her lone remaining rival, lawyer Marisa DeFranco, is an unknown to 82 percent of those polled.

The Globe poll also shows President Obama besting former Gov. Mitt Romney 49 percent to 33 in a likely November match-up. 

Despite Romney’s strong ties to the state, heavily Democratic Massachusetts is unlikely to be in play in the general election.
