Virginia's 10th congressional district election was one of the highest-profile United States House of Representatives elections of 2018, and the most competitive in Virginia, Democrat Jennifer Wexton, a lawyer and state lawmaker representing Loudoun County, ousted Republican two-term incumbent congresswoman Barbara Comstock. Virginia’s 10th District was one of the most expensive House races in the United States, with both campaigns spending a total of $11 million. Comstock’s loss meant that until the next voting cycle no Republicans would be representing the immediate Washington region.
