(CNN) - A new poll conducted entirely after Anthony Weiner admitted to lewd chats a year after such sexting forced him to resign from Congress indicates that the Democratic New York City mayoral candidate's support among voters has dropped significantly.
According to an NBC 4 New York/Wall Street Journal/Marist survey released Thursday, 16% of registered Democrats now say they'd vote for Weiner for mayor in September's Democratic primary. That's down nine percentage points from the last Marist survey, conducted in late June. In that poll Weiner stood at 25%, with New York City Council Speaker Christine Quinn at 20%. Now Quinn leads Weiner 25%-16%.

The new poll was conducted Wednesday, one day after Weiner held a news conference to admit to sending lusty messages more than a year after resigning from Congress for the same dubious habits.
Positive views of Weiner have nosedived, according to the poll. Fifty-five percent now say they have an unfavorable view of the former seven-term congressman who represented parts of Brooklyn and Queens, up 19 points from late last month. And his favorable rating has dropped during the same time period 22-points, to 30%.
"For many Democrats the latest revelations about Anthony Weiner are more of the same, only more so," says Dr. Lee M. Miringoff, Director of The Marist College Institute for Public Opinion. "Weiner has lost his lead and his negatives are at an all-time high."
Some of his opponents in the race for the Democratic mayoral nomination, as well as some other New York City politicians, have called on Weiner to drop his bid. Do New Yorkers agree?
Forty-seven percent of Democrats questioned say Weiner should stay in the race, with 43% saying he needs to call it quits and one in ten unsure.
Does Weiner's sexting matter to Democratic voters?
Forty-six percent say his on-line relationships with other women will impact their vote, with 49% saying they will make only a minor impact or not matter at all.
In Tuesday's extraordinary news conference, Weiner and his wife, Huma Abedin, pleaded for voters to forgive the embattled candidate. Unlike his public resignation two years ago, Abedin spoke up for her husband this week, saying she's pushing beyond Weiner's problems and urged others to do the same.

But it appears her commitment to her husband does little to help his mayoral chances. Nearly three-quarters of Democrats questioned say Abedin's support has no impact on how much trust they have in Weiner to be mayor, with 15% saying her backing makes them more likely to trust him and 12% saying it makes them less likely to do so.
Does Weiner deserve another chance?
Forty-seven percent say yes, with 45% saying he does not have the character to be mayor.

In the Democratic horserace, there's a slight gender divide, with Quinn edging out Weiner 24%-20% among men and leading 26%-3% among women.
In the overall race, after Quinn at 25% and Weiner at 16%, former New York City Comptroller Bill Thompson and Public Advocate Bill de Blasio both stand at 14%, with the remaining Democratic candidates in single digits and nearly one in five undecided.
The NBC 4 New York/Wall Street Journal/Marist poll was conducted on July 24, with 1,199 New York City adults, including 970 registered voters and 551 registered Democrats, questioned by telephone. The survey's sampling error for questions of registered Democrats is plus or minus 4.2 percentage points.
