But none of the 1,157 inmates can actually vote. A lawsuit filed Monday by the Florida branch of the American Civil Liberties Union argues that the county’s use of “prison gerrymandering,” the practice of counting inmates as residents of their correctional facilities when drawing legislative districts, is inflating the political influence of the non-prison population of District 3 and diluting the political influence of the rest of the county.
