(CNN) - In one of the most closely watched Senate contests, a new poll indicates Republican Sen. Scott Brown and Democrat Elizabeth Warren are still running neck-and-neck in the race for the Massachusetts seat.
Brown, a first-term incumbent, has the support of 37% of voters, while his opponent carries 35%, according to a survey conducted by the University of New Hampshire Survey Center and released by The Boston Globe on Sunday.

The two-percentage-point margin falls well within the sampling error and represents a statistical tie. Meanwhile, 26% of voters said they were undecided, according to the poll.
While support falls mainly along party lines - Warren takes 63% of Democrats and Brown has 86% of Republicans - the incumbent senator is leading among the crucial voting bloc of independents, with 42% to Warren's 14%.
Breaking down the results further, 43% of voters said they see Brown as the strongest leader to Warren's 31%. In addition, nearly half (49%) said Brown has the most bipartisan appeal, while less than a third of voters (27%) said Warren would be the best at working across the aisle.
However, a plurality (44%) said Warren - Obama's former consumer protection adviser - would do more to help "working people," compared to 35% who said the same about Brown. The statistic comes as good news to Warren's campaign, which has aggressively pushed to portray the candidate as the one most aligned with middle class workers.
The poll is the latest in a series of surveys in recent months that show a similar pattern of the two candidates statistically tied, with Brown slightly ahead.
Democrats see the race as a chance to recapture a Senate seat that was taken by the GOP in the 2010 special election held to replace the late Ted Kennedy.
Both campaigns have raised and spent millions, despite seven months remaining until the November election. The candidates have also gained fame by their shared opposition towards third-party spending, pledging to deduct money from their own campaigns should outside groups take out ad buys in support of their candidacies.
For the poll, the University of New Hampshire Survey Center interviewed 544 randomly selected likely voters by phone between March 21 and March 27. The poll has a sampling error of plus or minus 4.2 percentage points.
