Demcoratic mayoral nominee Bill de Blasio holds a wide lead over his GOP rival Joe Lhota, leading him by nearly every measure save for taxes, a Quinnipiac University poll today found.

De Blasio, the city’s public advocate, leads Lhota, the former MTA chairman under Gov. Andrew Cuomo, 66 percent to 25 percent, the poll found.

The survey also found a wide racial gap between de Blasio and Lhota.

Among white voters, de Blasio leads 52 percent to 40 percent.

But among black voters, his lead is up to 90 percent, with only 3 percent backing Lhota. De Blasio also leads among Hispanic voters 68 percent to 18 percent.

Lhota’s only silver lining is that he has a lead among the city’s small Republican enrollment, 79 percent to 15 percent. Among independent voters, de Blasio holds 53 percent to 36 percent advantage.

“The same kind of coalition that won Public Advocate Bill de Blasio the Democratic primary is working for him in the general election campaign,” said Maurice Carroll, director of the Quinnipiac University Polling Institute. “He’s OK among white voters and gang-busters among black and Hispanic voters. “In these opening days of the campaign, Independence Party candidate Adolfo Carrion is no more than a footnote.”

The poll comes more than a week after de Blasio’s victory in the Democratic primary and former city comptroller Bill Thompson backed away from a run off challenge.

Lhota handily defeated supermarket magnate John Catsimatidis in a Republican primary.

The survey of 891 voters was conducted from Sept. 15 through Sept. 18. It has a margin of error of 3.3 percentage points.
