Blue Mass Group commissioned the excellent folks at Research 2000 (the same ones who do Daily Kos's polling) to poll likely Democratic voters a couple of days after Monday night's televised debate to see where things stand in the MA Senate race. The results show that Martha Coakley has an impressive lead over all three of her rivals. So the debate doesn't seem to have moved the race significantly -- if anything, our poll shows that Coakley's lead has grown a bit since the last pre-debate poll.
400 likely Democratic primary voters polled Oct 28-29. Margin of error = +/- 5%
"If the Democratic Primary for U.S. Senate were held today, which of the following candidates would you vote for?"
Coakley: 42%
Capuano: 16%
Pagliuca: 15%
Khazei: 5%
Undecided: 22%
Note that, if these numbers hold up, even if Capuano picks up every single undecided voter, Coakley still wins.
