-Brown’s approval rating has dipped to just 46%, with 45% of voters unhappy with his job performance. Meanwhile Warren’s favorability numbers continue improving as the campaign progresses. 52% of voters now have a positive opinion of her to just 43% with a negative one.

-Warren is now leading Brown with both women (55-40) and men (50-48). She also has the advantage with voters in every age group. She’s cut Brown’s lead with independents almost in half over the last two months, from 26 points in August to now just 15 points. And she has the Democratic base pretty unified around her with 81% planning to vote for her compared to only 14% who are siding with Brown.

-Barack Obama leads the Presidential race in the state 57-39, a small improvement from last week when he led only 55-41. He’s winning over 16% of the Republican vote in the state, more than Mitt Romney’s 11% share with Democrats.
