There's good news and bad news for Democratic hopes of taking down Scott Brown in our newest Massachusetts poll. The good news is that Brown's approval numbers are starting to decline. What was a +24 approval spread in December at 53/29 has now been cut in half to +12 at 48/36. The bad news is that with no standout Democratic candidates ready to make the race yet Brown leads 8 hypothetical opponents we tested against him by anywhere from 9 to 25 points.

The good news is that Brown is losing ground in MA. Even against unknown candidate, he does not reach 50 %. The bad news is that PPP decided to poll people who are not candidates, and probably will not be (including Martha Coakley).
What is obvious at this point is that people only fare as well as their name recognition: Capuano and Markey are the only one to go higher than 35 %. Warren, is only at 32 and Khazei at 31, while Bob Massie and Setti Warren (certainly those who have the lowest name recognition) are basically tied. Now, those two, who with Khazei are the only one in the list running, have potential if they can become known, given that Brown does not reach the 50 % bar with them. And if any other candidate wants to run, please say so rather than waiting the redistricting.
