Scott Brown and Elizabeth Warren continue to battle for the Mass. Senate seat. | AP Photos Poll: Brown leads Warren by 9 points

Sen. Scott Brown (R-Mass.) has opened up a 9-percentage-point lead over Elizabeth Warren, according to a new poll that differs from several other recent surveys.

Forty-nine percent of respondents in a Suffolk University/7News poll on Thursday said they would vote for Brown, while 40 percent said they would back his Democratic rival.


A recent WBUR poll had shown Warren with a small lead over Brown, 46 percent to 43 percent, which fell within the poll’s margin of error of 4.4 percentage points. This survey came after a number of other polls in December that also showed the Democrat pulling ahead of the senator.

In the Suffolk University/7News poll, Brown had a 52 percent favorable and 28 percent unfavorable rating, while Warren had a 35 percent favorable and 28 percent unfavorable rating.

The majority of the general election voters in Massachusetts said they would prefer to see one Democratic and one Republican senator representing their state — 60 percent said it was beneficial to have a member of each political party representing them in Washington, while 36 percent disagreed.

The Suffolk University/7News poll was conducted Feb. 11-15 among 600 Massachusetts registered voters and has a margin of error of plus or minus 4 percentage points.
