Anthony Weiner vowed Sunday to stay in the New York City mayor’s race, as he confirmed his campaign manager quit and his top rival said he was not qualified to lead the nation’s most populous city, reports USA Today. Weiner admitted that campaign manager Danny Kedem resigned after revelations came out last week that he continued to send salacious messages online to women, even after resigning from Congress in 2011. With Kedem out of the already shrunken campaign staff, the longshot City Hall bid appeared to be unraveling. Weiner stood firm despite his travails yesterday, spending much of the day in his apartment shooting a campaign ad. “I am running for mayor of the city of New York, and I plan on winning,” Weiner told the New York Post Saturday. Meanwhile, David Axelrod, a former senior adviser to President Obama, said Sunday that former Rep. Anthony Weiner is “delusional” and should drop out of the race for New York City mayor, according to The Hill.
