Democrat Elizabeth Warren holds a small lead over Republican Sen. Scott Brown in the Massachusetts Senate race, according to a poll released Monday night -- the third in two days showing Warren ahead.
The Suffolk University survey finds Warren leading Brown by four percentage points, 48 percent to 44 percent. The survey's margin of error is four percentage points.
Though Warren leads, Brown is viewed slightly more favorably in the new poll. Brown is viewed favorably by 60 percent of the poll's respondents and unfavorably by 29 percent. Warren was viewed favorably by 52 percent and unfavorably by 33 percent.
In addition, Brown received significant support from voters who say they will support President Barack Obama in the presidential race. Among Obama voters, 19 percent said they would support Brown in the Senate race.
The Suffolk poll was conducted from Sept. 13 to Sept. 16 and surveyed 600 likely voters. The poll was conducted using live interviews over landlines and cellphones.
Two other polls, both released on Sunday, also found Warren gaining. A Western New England University poll found Warren leading by six percentage points, while a Public Policy Polling survey found her leading by two percentage points.
HuffPost Pollster's estimate on the race, which takes into account all available public polling, continues to show less than a percentage point separating the two candidates, at 46.3 percent for Warren and 45.8 percent for Brown.
