PPP's newest poll on the Massachusetts Senate race finds Scott Brown opening up a 5 point lead, 49-44. This is the first time Brown has led in one of our polls since June of 2011. Our last poll, in June of this year, found a tie and the two before that had modest leads for Elizabeth Warren.
Brown continues to do well because of his personal popularity and because voters see him as different from the Republican Party as a whole. 53% of voters approve of the job he's doing to 36% who disapprove. Incumbents with those kinds of approval numbers generally don't lose. Brown's approval has improved a net 14 points from March when he was at +3 (45/42). Warren's numbers are headed in the other direction. On that poll her favorability was 46/33 and now it's 46/43- her negatives have risen 10 points over the last five months while her positives have remained unchanged.
As the electorate gets to know Elizabeth Warren, they like her less and less.
