State Sen. Scott Brown (R), buoyed by a new Rasmussen poll that shows him trailing by 9 points in the Massachusetts Senate special election, says he has the momentum to carry him to an upset win in two weeks.

"I was 30 points down a month ago, and 9 points now," Brown told RCP in an interview this afternoon. "While I'm certainly happy, I don't want to have anyone be complacent because there's still two weeks. It's not over until it's over. And I'm going to treat it that way until 8:01 on January 19."

Brown did not shy away from voicing Republican positions on the major issues of the day, but said he's been successful in Massachusetts by being an independent voice, and one not beholden to entrenched interests. That was especially the case last in 2008, when he said he carried his state Senate district by a wider margin than President Obama or John Kerry did.

"I'm not taking anyone's vote for granted," he said. "I think it'll be closer than 9 points, certainly. And if everybody gets out and votes, I may even have the chance to win."

We'll have more from the interview tomorrow.
