Since it was built in 1931, River House, the swank and secluded Art Deco palace behind wrought-iron gates at the dead end of East 52nd Street, has topped the short list of exclusive (and very expensive) co-ops along the East River waterfront. Home to Henry Kissinger (and Pete Peterson until recently), the building boasts three 20 million+ listings at the moment, including a large tower duplex owned by real estate mogul Francesco Galesi, which was boldly listed for $50 million almost three years ago but has since come down to $35 million. (Other apartments for sale include Laura Pels' terraced third-floor unit for $29 million, and the opulent maisonette of Chicago producer Marty Richards.) Naturally, it's also home to a long list of heavy-hitting political donors. After the jump, a list of what some River House residents have done with their cash in this year's battle for the White House.
