A new poll released today by ARG shows the Massachusetts Senate race to be a dead heat three days before the special election. Republican Scott Brown led Democrat Martha Coakley by three points, 48-45, among 600 likely voters surveyed by ARG on Thursday and Friday. The poll’s margin of error is 4%.
Democrats are going all out this weekend to boost support and drive turnout for Coakley as political observers increasingly see the race slipping away from her in the final days. President Obama is heading to Massachusetts to headline a rally for Coakley tomorrow afternoon, having already recorded a robo-call for Coakley last week. Republicans, meanwhile, are dumping millions into the state in support of Brown, hoping for a surprise upset in the race to fill Ted Kennedy’s old seat in the Senate.
