Coakley is supported by 77% of Democrats while Brown picks up the vote from 88% of Republicans. Among voters not affiliated with either major party, Brown leads 71% to 23%. To be clear, this lead is among unaffiliated voters who are likely to participate in the special election.An earlier Rasmussen poll (which figured things marginally differently) had a 50-41 race in Coakley's favor. Notwithstanding the differences between the two polls, Brown seems to be closing the gap somewhat.
An interesting point about enthusiasm:
The new Rasmussen Reports poll shows that Brown is ahead by two percentage points among those who are absolutely certain they will vote. A week ago, he trailed by two among those certain to vote.See Michael Barone for more.
