# 2018 United States Senate election in Delaware

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. 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.

## Background

Three-term Democratic Senator Tom Carper was reelected with 66% of the vote in 2012 against Republican Kevin Wade.
Carper, the incumbent U.S. senator, was challenged in the Democratic primary by Dover activist Kerri Evelyn Harris. Carper previously faced a primary challenge in the 2012 election from businessman Keith Spanarelli. However, Carper defeated Spanarelli by around 70 points. Carper went on to defeat Harris by around 30 points. It was the most competitive Democratic U.S. Senate primary in Delaware in two decades.
The main declared candidates in the Republican primary were Sussex County councilman Rob Arlett and businessman Gene Truono, with a perennial candidacy from businessman Rocky De La Fuente, who also ran for Senate in seven other states. Another candidate withdrew before the primary. Rob Arlett defeated Gene Truono in a landslide to win the Republican nomination.

### Debates

Councilman Rob Arlett and businessman Gene Truono had four debates in total. They were normally live streamed on Facebook and uploaded to YouTube. A fifth debate was planned, but Truono withdrew from the debate because he the organizers refused to give him control over what questions could not be asked. Instead organizers held a forum with all the other candidates for the U.S. Senate and other state offices. Five candidates attended that forum.
