WASHINGTON (AP) — Muriel Bowser won the District of Columbia’s Democratic mayoral primary Tuesday, defeating incumbent Vincent Gray in a race defined by a scandal involving Gray’s campaign four years ago.

Bowser tapped into an electorate that tired of the allegations surrounding Gray. Five people who worked on the mayor’s 2010 campaign have pleaded guilty to felonies, and Bowser said the city needed to move away from a mayor who faces potential criminal charges.
