Democrat Elizabeth Warren has opened up a lead against Republican incumbent Scott Brown for the first time in their U.S. Senate showdown, but a barrage of attack ads appears to have damaged Warren and Brown’s standing among Massachusetts voters, a new University of Massachusetts at Lowell/Boston Herald poll shows.
Warren leads Brown by a 49-42 percent margin, outside the poll’s margin of error of plus or minus 5.3 percentage points. That number includes voters who say they are “leaning” for either candidate. But even without the “leaners,” Warren still leads by a 46-41 percent margin, barely within the margin of error.
The poll of 505 registered Massachusetts voters was conducted for UMass-Lowell by Princeton Survey Research from Dec. 1 – Dec. 6, and shows Warren with her largest lead yet in the campaign. A UMass-Lowell/Boston Herald poll taken in late September showed Brown ahead by a 41-38 percent margin, so the new poll represents a 10-point swing in Warren’s favor in less than two months.
