“Farragut North” ends its campaign this weekend at the Silver Spring Stage. Directed by Bridget Muehlberger, Beau Willimon’s exploration of backroom politics served as the inspiration for George Clooney’s 2011 film “The Ides of March.” Montgomery County theatergoers can cast their vote through Saturday at the theater, located in the Woodmoor Shopping Center, 10145 Colesville Road, Silver Spring.
