He is imploding. The fact that his unfavorable number is now 45% to 44% favorable is a HUGE shift in a short time. It is hard to account for as there was not much done between the two polls. It may be that the dirty tricks twitter nonsense hit him more than it might most as his top asset was the perception that he was a nice guy, so people were willing to ignore their disagreements.
Not to mention, I suspect that the MA media will not be able to spin this as Brown still being the most popular MA elected official
Brown's numbers suggest that, even if Warren implodes and another Democrat wins, Brown is likely no longer the unbeatable frontrunner.
But, Brown's own concern - Obama won't play basketball with him.
