The Research 2000 Massachusetts Poll was conducted from January 12 through January 13, 2010. A total of 500 likely voters who vote regularly in state elections were interviewed statewide by telephone.
Cross-tabs:

Partisan breakdown is 42% Independents, 40% Democrats, 18% Republicans. Women support Coakley by about 20 points. Men narrowly support Brown.
Almost all the white vote is decided, which should leave room for growth for Coakley.
