Republican Scott Brown leads Democrat Martha Coakley 48% to 45% in the special Massachusetts US Senate race to replace Senator Ted Kennedy in a telephone survey conducted January 12-14 among 600 likely voters in Massachusetts saying they will definitely vote in the special election on January 19.
Brown leads Coakley 94% to 1% among registered Republicans and he leads 58% to 37% among unenrolled voters. Coakley leads Brown 71% to 20% among registered Democrats. A total of 8% of Democrats and 5% of Republicans remain undecided.
Brown leads 54% to 39% among men while Coakley leads 50% to 44% among women.
Brown leads 52% to 42% among likely voters age 18 to 49 and Coakley leads 47% to 46% among voters 50 and older.
A total of 9% of likely voters say they have already voted by absentee ballot, with Brown leading Coakley 58% to 42%.
The interviews for this survey were conducted January 12-14, 2010 among a statewide random sample of 600 likely voters in Massachusetts. To be included in the sample as a likely voter, adults 18 years and older in telephone households (1) had to be registered to vote, (2) rate their chances as a "9" or "10" on a scale of 1 to 10, with "1" meaning definitely not vote and "10" meaning definitely vote on January 19, and (3) to also say they would definitely vote on January 19 at the conclusion of the interview. A total of 263 respondents identified as likely voters are registered to vote as Democrats, 122 as Republicans, 213 as unenrolled voters, and 2 with other parties.
The theoretical margin of error for the total sample of 600 likely voters is plus or minus 4 percentage points, 95% of the time, on questions where opinion is evenly split. The theoretical margin of error will be larger for any sub-samples.
