Senate Ratings

January 18, 2010 · 8:02 AM EST

While special elections often come down to turnout – and they therefore are more difficult to predict than normal elections – the combination of public and private survey research and anecdotal information now strongly suggests that Republican Scott Brown will defeat Democrat Martha Coakley in tomorrow’s race to fill the remainder of the late-Sen. Edward Kennedy’s seat.

Brown is running extremely well with Independents in the Bay State, and unless Democratic turnout exceeds everyone’s expectations, Brown is headed for a comfortable win. Move from Toss-Up to Lean Takeover.
