Campaign manager quits but Anthony Weiner insists he won't leave race for NYC mayor Mr Weiner confirmed that Mr Kedem has resigned but wouldn't say who is replacing him. We have an amazing staff, but this isn't about the people working on the campaign. It's about the people we're campaigning for," he said after speaking at a Brooklyn church. Meanwhile on Sunday, his rival for the Democratic nomination, Christine Quinn, speaker of the New York City Council, said Mr Weiner has shown "a pattern of reckless behavior, an inability to tell the truth and a real lack of maturity and responsibility." "I don't think he should be mayor, and I think the voters, if he stays in the race, will make that clear," Ms Quinn said on NBC's "Meet the Press." Mr Weiner was forced to discuss his online behavior this past week after a gossip website printed excerpts of conversations Mr Weiner had with Indiana college student Sydney Leathers last summer. With his wife, Huma Abedin, a former top aide to ex-Secretary of State Hillary Rodham Clinton, alongside, Mr Weiner apologised and promised that the "behavior is behind me." He later admitted that he traded racy messages with at least three women since leaving office. He vowed to stay in the race, saying he believed "people care more about their futures than my past with my wife and my embarrassing things." Ms Quinn led the race before mr Weiner jumped in but slipped behind him in most polls over the past two months. But a one-day poll conducted after the latest revelations has her leading Mr Weiner in the race for the Democratic nomination. The mayoral primary is on September 10, and the general election is November 5. Mr Kedem had managed the re-election of John DeStefano Jr. to a 10th term as mayor of New Haven in 2011 and worked on Hillary Clinton's failed 2008 presidential campaign.
