A fourth poll has brought good news for Elizabeth Warren this week, who barely trailed Massachusetts Sen. Scott Brown through the summer but has recently opened up a small lead over the Republican she is trying to unseat in November.
A WBUR poll released late Wednesday showed the Harvard professor with a 5-point advantage over Mr. Brown, leading him 45 to 40 percent with 12 percent of respondents saying they were undecided.
Earlier this week, three other polls also gave Mrs. Warren a small lead. A Suffolk University/WHDH News 7 poll had her ahead by 4 percent, a Public Policy Polling Survey had her up by2 percent and a poll commissioned by MassLive.com/The Republican showed a 6-point lead.
The two will face off Thursday night, in the first of three debates scheduled to take place before the November election.
The WBUR poll was conducted Sept. 15-17 among 507 likely Massachusetts voters and has a 4.4 percent margin of error.
