A day after two polls showed a tight race for Eliot Spitzer, a new Siena College/New York Times poll shows him maintaining a double-digit lead.

The poll shows Spitzer leading Manhattan Borough President Scott Stringer 50-35 percent in the Democratic primary for city comptroller.

A Quinnipiac poll on Thursday showed them tied at 46, while another showed Spitzer at 46 and Stringer at 43.

The Siena poll echoed other polling that has shown Public Advocate Bill de Blasio taking the lead in the mayoral primary. He leads 2009 nominee Bill Thompson 32-18 percent, with City Council Speaker Christine Quinn at 17 percent and former congressman Anthony Weiner at 11 percent.

Quinnipiac showed de Blasio leading Quinn 36-21 percent -- approaching the 40 percent of the vote he would need to avoid a runoff.

The primary is Sept. 10.
