PPP:
Elizabeth Warren has had an incredibly successful launch to her Senate campaign and actually leads Scott Brown now by a 46-44 margin, erasing what was a 15 point deficit the last time we polled the state in early June.
Warren's gone from 38% name recognition to 62% over the last three months and she's made a good first impression on pretty much everyone who's developed an opinion about her during that period of time. What was a 21/17 favorability rating in June is now 40/22- in other words she's increased the voters with a positive opinion of her by 19% while her negatives have risen only 5%.
The surprising movement toward Warren has a lot to do with her but it also has a lot to do with Scott Brown. We now find a slight plurality of voters in the state disapproving of him- 45%, compared to only 44% approving. We have seen a steady decline in Brown's numbers over the last 9 months.
