Polls: Who's in the lead in New York City mayor's race?

(CNN) - Who's ahead in the race for New York City mayor?

The answer depends on which poll you're reading.

Two recent surveys indicated former Rep. Anthony Weiner on top of the pack in the hunt for the Democratic mayoral nomination. But a new poll puts Weiner, who is making a very public bid for political redemption, in second, behind City Council Speaker Christine Quinn, with less than two months to go until the September primary.

According to a New York Times/Siena College survey released Thursday morning, Quinn has the backing of 27% of registered New York City Democrats, with Weiner at 18%. Former Comptroller William Thompson and Public Advocate Bill de Blasio are at 11%, with the rest of the field in single digits. If victorious in November's general election, Quinn would become New York City's first female and first openly gay mayor.

Weiner was in his seventh term in Congress representing parts of the New York City boroughs of Queens and Brooklyn when he resigned from the House in 2011 amid scandal over lewd photos sent via Twitter. In May, Weiner announced his bid for a second chance in politics. According to the poll, only 24% of Democrats surveyed have a favorable opinion of Weiner, with 36% holding an unfavorable view. But nearly six in ten say he deserves a second chance.

While the New York Times/Siena College poll indicates Quinn in the lead, it was a different story in a Quinnipiac University survey released at the beginning of the week. That poll put Weiner at 25%, with Quinn at 22%, far ahead of the rest of the field. Weiner's three point margin over Quinn was within the survey's sampling error.

And a Marist College poll conducted late last month indicated Weiner with a five point advantage over Quinn, which was within that survey's sampling error.

The New York Times/Siena poll also indicates nearly six in ten city Democrats say that former New York Gov. Eliot Spitzer deserves a second chance. Spitzer, who resigned as governor in 2008 after revelations he spent thousands of dollars on prostitutes, jumped into the race for New York City comptroller just over a week ago. The survey did not ask a question about the race for comptroller, which is the city's chief budget office.

But Spitzer held a double digit lead over his main competitor for the Democratic nomination, Manhattan Borough President Scott Stringer, in the Quinnipiac survey and a nine point lead over Stringer in an NBC 4/Wall Street Journal/Marist poll released last week.

The New York Times/Siena College survey was conducted July 9-15, with 1,010 registered New York City voters, including 610 registered Democrats. The survey's overall sampling error is plus or minus 3.1 percentage points, with a sampling error of plus or minus four percentage points for questions only of Democrats.
