In the most heavily Democratic state in the union, Scott Brown is holding his own so far against far left darling Elizabeth Warren.

A new poll out by WBUR shows the race virtually tied:

A new WBUR poll shows U.S. Sen. Scott Brown and Democratic Senate candidate Elizabeth Warren running neck and neck. Forty-six percent of people polled said they would vote for Warren compared to 43 percent for Brown. The three-point lead is within the margin of error.

Political newcomer Warren surprised the establishment when she raised millions of dollars in both of the last two quarters. She's used that money to buy TV ads, and based on conversations with voters, the ads seem to be working.

"I just feel more comfortable with her because I know she's going to fight for what I want," said
Belmont Democrat Lucille Duddy. Duddy knows everything she does about Warren from watching those television spots.

Pollster Steve Koczela said of Warren, "She's gotten her name out there. Now many more people have a view of her and she's translated that into higher support than she had before."

Koczela leads the polling group at the independent think-tank MassINC. He conducted the poll for WBUR.

"[Warren] really came out of the gate fast and there was some question as to whether or not she was going to be able to maintain the momentum that she started out with," he said. "And what this poll has shown is that she has been able to maintain that momentum."

Some of the internals are interesting.

- Warren is +28 with 18-29-year-olds
- Brown is +24 with 30-44-year-olds
- Brown is +2 with 45-59-year-olds

- Warren is +23 with 60-and-over respondents

- Brown's rating is 50/29 favorability/unfavorability
- Warren's rating is 39/29 favorability/unfavorability

Both candidates are going to be well financed. But with a state expected to go heavily for Obama, Brown has his work cut out for him.

It should be a donnybrook all the way to November.
