Two just-released polls find that progressive champion Elizabeth Warren is now leading incumbent Senator Scott Brown (R) in the Massachusetts Senate race.

First, here’s a poll from theAi??Western New England University Polling Institute:

Of the 444 likely voters interviewed for the survey, 50 percent said they would support Warren if the election was held today, 44 percent said Brown, and six percent said they were undecided. Among the larger sample of 545 registered voters, Warren led Brown by 12 points, 53 percent to 41 percent, with six percent undecided. The margin of sampling error for the sample of likely voters is plus or minus 4.6 percentage points, and the margin of error for the sample of all registered voters is plus or minus 4.2 percentage points.

Second, here’s the results from a new Public Policy Polling survey:

Things have been going Elizabeth Warren’s way in the Massachusetts Senate race over the last month. She’s gained 7 points and now leads Scott Brown 48-46 after trailing him by a 49-44 margin on our last poll.

Warren’s lead is likely a result from her excellent convention speech and voters’ increasingly realizing that Brown has been a shill for Wall Street during his time in the Senate.
