Two new polls released Sunday indicate a tight race between Senator Scott Brown, a Republican, and his challenger, Democrat Elizabeth Warren, with either candidate capable of pulling out a victory on Tuesday.
One of the polls, by the UMass Lowell Center for Public Opinion and the Boston Herald, showed Brown ahead by one percentage point, 49 percent to 48 percent. The second survey, by the Western New England University Polling Institute and the Springfield Republican newspaper, showed Warren leading Brown by four percentage points, 50 percent to 46 percent.
The UMass Lowell poll surveyed 956 Massachusetts registered voters between Wednesday and Saturday and has a margin of error of plus or minus 4.1 percentage points. The results showing Brown with a one-point lead were based on a sample of 800 voters who were deemed likely to vote.
The Western New England poll of 535 likely voters was conducted between Oct. 26 and Nov. 1 and has a margin of error of plus or minus 4 percentage points.
In the presidential race, the UMass Lowell poll showed President Obama trouncing Mitt Romney in Massachusetts, with 57 percent of likely voters favoring Obama and 37 percent favoring Romney.
