The 2018 United States Senate election in Delaware took place on November 6, 2018, to elect a member of the United States Senate to represent the State of Delaware, concurrently with other elections to the United States Senate, elections to the United States House of Representatives, and various state and local elections.
The primary for this U.S. Senate election was held on Thursday, September 6, 2018.[1] The Democratic Party nominated incumbent U.S. Senator Tom Carper and the Republican Party nominated Sussex County Councilman Rob Arlett.
Incumbent Democratic Senator Tom Carper was re-elected to a fourth, and ultimately final, term. Despite Carper's victory, Arlett managed to flip Sussex County, typically a reliably Republican county in Delaware. This subsequently marked the first time Carper lost the county since his first election to the Senate in 2000.
