Rabhi defeats 12-year incumbent in Ann Arbor mayoral primary. ANN ARBOR — Ann Arbor appears poised to move further toward progressive policies after democratic socialist Yousef Rabhi defeated longtime Mayor Christopher Taylor in Tuesday’s Democratic primary. Rabhi, 38, previously represented Ann Arbor in the State House of Representatives and served as Democratic floor leader. “The people of Ann Arbor sent a message,” Rabhi said. Ann Arbor operates under a Council-manager structure in which the mayor’s direct administrative authority is limited.
