Massachusetts Senate Poll

Scott Brown leads Martha Coakley 51-46 in our final Massachusetts Senate poll, an advantage that is within the margin of error for the poll.

Over the last week Brown has continued his dominance with independents and increased his ability to win over Obama voters as Coakley's favorability numbers have declined into negative territory. At the same time Democratic leaning voters have started to take more interest in the election, a trend that if it continues in the final 36 hours of the campaign could put her over the finish line.

Here's what we found:

-Brown is up 64-32 with independents and is winning 20% of the vote from people who supported Barack Obama in 2008 while Coakley is getting just 4% of the McCain vote.

-Brown's voters continue to be much more enthusiastic than Coakley's. 80% of his say they're 'very excited' about voting Tuesday while only 60% of hers express that sentiment. But the likely electorate now reports having voted for Barack Obama by 19 points, up from 16 a week ago, and a much smaller drop from his 26 point victory in the state than was seen in Virginia.

-Those planning to turn out continue to be skeptical of the Democratic health care plan, saying they oppose it by a 48/40 margin.

-Coakley's favorability dropped from 50% to 44% after a week filled with perceived missteps. Brown's negatives went up a lot but his positives only actually went from 57% to 56%, an indication that attacks against him may have been most effective with voters already planning to support Coakley but ambivalent toward Brown.

-56% of voters in the state think Brown has made a strong case for why he should be elected while just 41% say the same of Coakley. Even among Coakley's supporters only 73% think she's made the argument for herself, while 94% of Brown's supporters think he has.
