Question P :
Government :
vte :
The 2018 United States Senate election in Maryland took place on November 6, 2018, in order to elect a member of the United States Senate to represent the State of Maryland. It was held concurrently with other elections to the United States Senate, elections to the United States House of Representatives, and various state and local elections. Incumbent Democratic U.S. Senator Ben Cardin was re-elected to a third and ultimately final term by a landslide margin of almost 35 points, the largest margin in any election for this seat since Maryland began holding direct elections for Senate in 1913.
The primary election for the Senate race was held on June 26, 2018. The incumbent, Ben Cardin, won the Democratic Party primary. In the general election, Cardin was reelected to a third term. Tony Campbell, a professor of political science at Towson University and former Army Chaplain, won the Republican Party primary. If elected, Campbell would have become Maryland's first African-American U.S. Senator. Businessman Neal Simon ran as an independent and Arvin Vohra was the Libertarian Party nominee in the general election. There were also several official write-in candidates. With Republican governor Larry Hogan winning re-election in the same year, this was the first election since 1974 in which Maryland simultaneously voted for a gubernatorial nominee and a U.S. Senate nominee of opposite parties.
