Democrat Elizabeth Warren runs neck-and-neck with Sen. Scott Brown, R-Mass., according to a survey conducted late last month.
Warren leads Brown 43 percent to 41 percent in the survey, which was conducted by the MassINC Polling Group, a nonpartisan organization that conducts quarterly polls in the Bay State.
The survey was conducted in late April, before the controversy about Warren's Native American heritage had reached its boiling point. Warren's campaign has struggled to respond to questions raised by the Brown camp about her listing as a minority in a directory of law professors.
Forty-six percent of registered voters polled had a favorable view of Brown, while 33 percent held an unfavorable view of the senator. Thirty-four percent held a favorable view of Warren while 25 percent held an unfavorable view of the Democratic challenger.
The MassINC Polling Group survey of 438 Massachusetts voters was conducted from April 25 to April 28 and carries a margin of error +/- 4.7 percentage points.
