Via Quinnipiac:

With 47 percent of black voters and 44 percent of women voters, New York City Public Advocate Bill de Blasio surges to 43 percent of likely voters in the Democratic primary for mayor, passing the 40 percent cutoff and possibly avoiding a runoff, according to a Quinnipiac University poll released today.

Former City Comptroller and 2009 Democratic nominee William Thompson is at 20 percent, with 18 percent for City Council Speaker Christine Quinn, 7 percent for former U.S. Rep. Anthony Weiner, 4 percent for Comptroller John Liu, 1 percent for former Council member Sal Albanese and 8 percent undecided.

This compares to results of an August 28 survey by the independent Quinnipiac University which showed de Blasio at 36 percent, with 21 percent for Quinn, 20 percent for Thompson, 8 percent for Weiner and 6 percent for Liu.
