Another poll on the Massachusetts Senate race, released this afternoon, puts Senator Scott brown and Democratic challenger Elizabeth Warren in a dead heat, with Warren holding a 40-38 lead.
The MassPulse Quarterly Poll of 500 residents aged 18 or older, conducted by The MassINC Polling Group, was the rare poll done in the depths of summer, between July 19 through July 22.

No one believes your phony polls. Even the unions are voting for Brown.
And your knowledge and experience of statistical analysis is? As for the Unions voting for Brown - in your dreams. So what is the basis for your comment? You do realize that this particular poll tends to favor the Republican? Where are the "real" polls? Incumbent with 38% and someone with no political experience leading. All with 100 days left. Did I mention that Elizabeth Warren has the largest active volunteer group in 100 years of history for the commonwealth?
