Sen. Scott Brown (R-Mass.) holds a 1-point lead over Democrat Elizabeth WarrenElizabeth WarrenWarren: Education Dept lawyer may have violated conflict-of-interest laws Congress should think twice on the Israel Anti-Boycott Act Sanders plans to introduce single-payer bill in September MORE in a new poll released the day before the election.

The UMass-Lowell/Boston Herald poll gives Brown 49 percent support to Warren's 48 among likely voters. Brown's lead is within the poll's 4 percentage point margin of error, indicating this race is statistically tied.

Warren has gained momentum over the past few weeks, and that, coupled with President Obama's strong support in Massachusetts, seemed to indicate that voters will favor her on Election Day.

But this poll — and another from the Boston Globe, released last week, which put the two tied — paint a picture of a race as tight as ever.

This new Boston Herald poll does put the momentum in Warren's favor, however — it shows her increasing support since September, when she posted 45 percent support among likely voters to Brown's 49 percent.

The poll was conducted among 800 likely voters from Oct. 31-Nov. 3 and has a margin of error of plus or minus 4 percentage points.
