City Council Speaker Christine Quinn continues to lead the Democratic mayoral candidates by a huge margin, a poll reported yesterday.

The New York 1/Marist College survey put Quinn at 37 percent, ex-Comptroller Bill Thompson at 13, Public Advocate Bill de Blasio at 12 and Comptroller John Liu at 9.

Ex-MTA chief Joe Lhota led the GOP primary with 20 percent. His rivals were all in single digits.
