Nathan Lane will host an Obama fund-raiser attended by Vice President Joe Biden at the Bridgehampton home of Ellen Chesler and Matthew Mallow. The Aug. 24 event, called East End for Obama, will feature a performance by James Taylor, and hosts include actress Julianne Moore, “Sopranos” star Edie Falco and Jane Holzer. Explaining this is one of the few Obama fund-raisers in the Hamptons, Chesler wrote in an e-mail that the event “began in the arts community out East but has morphed into what we understand will be the major campaign event this summer in the Hamptons.” Tickets range from $500 to $10,000 to join the host committee and get a photo with Biden.
