Republican Mike Clancy has won the primary for Virginia’s 10th Congressional District, setting up a challenging race against the retiring Democratic incumbent, Rep. Jennifer Wexton. Clancy, a senior executive in the tech industry and a former Navy lawyer, secured the Republican nomination after defeating a field of other candidates. The district, which encompasses outer Washington, D.C. suburbs, has become increasingly Democratic in recent years, but the Cook Political Report rates it as only a likely Democratic hold in November.
