The 2016 United States House of Representatives election in Delaware was held on November 8, 2016, to elect the U.S. representative from the state of Delaware from Delaware's at-large congressional district. The election coincided with the 2016 U.S. presidential election, as well as other elections to the House of Representatives, elections to the United States Senate and various state and local elections. The primaries were held on September 13.
Democrat John Carney, the incumbent representative, did not run for reelection, instead successfully running for Governor of Delaware.[1] Democrat Lisa Blunt Rochester won the open seat on November 8.
Democrats Bryon Short, a member of the Delaware House of Representatives from Highland Woods, and Bryan Townsend, a member of the Delaware Senate from Newark, Delaware, had previously said they would run for the seat if Carney ran for governor.[1] [2] Following Carney's announcement that he would run for governor, both Short and Townsend declared their candidacies in the race to succeed him. Lisa Blunt Rochester, the former State Labor Secretary, also joined the race. Short later withdrew from the race, citing difficulties fundraising. Rochester won the primary with 43.8% of the vote.[3]
