WBUR Senate Poll: Warren Holds A Lead

As the candidates prepare for their first televised debate Thursday night, a new WBUR poll (PDFs — topline, crosstabs) finds Democrat Elizabeth Warren leading Republican incumbent U.S. Sen. Scott Brown, 45 percent to 40 percent. The survey of 507 likely Massachusetts voters has a 4.4 percent margin of error.

WBUR's poll is the fourth released this week that shows Warren gaining ground.
