U.S. senator before election Dick Durbin Democratic Elected U.S. Senator Dick Durbin Democratic

The 2020 United States Senate election in Illinois was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Illinois, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate, elections to the United States House of Representatives and various state and local elections and the Illinois Fair Tax. Incumbent Democratic Senator Dick Durbin, who had been Senate Minority Whip since 2015, won reelection to a fifth term in office, defeating Republican nominee Mark Curran.

Durbin decisively won re-election with 54.9% of the vote. Key to Durbin's landslide victory was the heavily populated and very Democratic Cook County home of Chicago, which he won by around 560,000 votes. Durbin also did well in the suburban, often called collar counties of Chicago, winning all of them except McHenry County. Durbin did well in Champaign County, home of the University of Illinois, and St. Clair County, where his birth home of East St. Louis is located. Nevertheless, this was Durbin's first election in which he failed to win the formerly Democratic-leaning rural Alexander County. Curran did well in most rural areas of the state, including winning rural Alexander County where a Republican hasn't won since 1972. Durbin became the first senator from Illinois to be elected five consecutive times since senators began being elected by popular vote in 1913.

Durbin flipped eight counties that he lost in 2014 that being DeKalb, DuPage, Kane, Kendall, McLean, Peoria, Will and Winnebago counties, but lost the counties of Alexander, Calhoun, Gallatin, Pulaski and Whiteside. ^[1]
