New York, NY —

After winning support from the city's Republican and Independent parties, Mayor Bloomberg is now vying for the endorsement of the Working Families Party. WNYC's Bob Hennelly has more.

REPORTER: It may seem like a long shot, since the Working Family's Party led fierce opposition to the mayor's push to repeal term limits. But in a robust shock-and-awe bid for a third term that features an early media blitz, the mayor's leaving no possible angle unexplored. And for the mayor there are strategic advantages to making the Democratic candidates work for the progressive labor group's ballot line and aggressive get-out-the-votes skills.

Under WFP rules to win the nod, a candidate must win support from two-thirds of the party's 115-member coordinating council. In 2005 Bloomberg failed to get WFP backing but did garner just enough union support to deny the ballot line to his Democratic rival Fernando Ferrer. For WNYC, I'm Bob Hennelly.
