NEW YORK -- The announcement came over the loudspeakers at the Park Slope Food Co-op shortly before noon: Sen. John Kerry was conceding. People looked at each other stricken over the soy milk and organic vegetables. Pilates instructor Rachel Priebe ran weeping from the store. "I'm heartbroken," said Priebe, 30, sobbing gently as she loaded her bicycle on a Brooklyn sidewalk. "The rest of the country must be pretty out of touch with reality."
