The 2018 United States Senate elections were held on November 6, 2018. Among the 100 seats, the 33 of Class 1 were contested in regular elections while 2 others were contested in special elections due to Senate vacancies in Minnesota and Mississippi. The winners were elected to 6-year terms running from January 3, 2019, to January 3, 2025. Senate Democrats had 26 seats up for election (including the seats of 2 independents who caucus with them), while Senate Republicans had 9 seats up for election.

To maintain their working majority of 50 senators and their party's vice president's tie-breaking vote, Republicans could only afford a net loss of 1 seat in these elections. The Republicans had a 52-48 majority after the 2016 elections, but they lost a seat in Alabama in December 2017 after Jeff Sessions resigned to become U.S. attorney general and Doug Jones, a Democrat, won in the subsequent special election. Three Republican-held seats were open as a result of retirements in Tennessee, Utah and Arizona. Although every Democratic incumbent ran for re-election, Democrats faced an extremely unfavorable map, defending 26 seats, of which 10 were in states won by Donald Trump in the 2016 presidential election, and 5 of those where Trump had won by more than 10%. Republicans, however, only had to defend 9 seats, of which only 1 was in a state won by Hillary Clinton in 2016.

The Republicans increased their majority by defeating Democratic incumbents in Florida, Indiana, Missouri, and North Dakota; and holding the open seats in Tennessee and Utah. In contrast, Democrats won 2 Republican-held seats, defeating an incumbent in Nevada and winning the open seat in Arizona.

The results for this election cycle were the only significant gains made by the Republicans in what was otherwise characterized as a "blue wave" election. The Republican gains in the Senate and the Democratic gains in the House marked the first mid-term election cycle since 1970 in which the president's party made net gains in one chamber of Congress while suffering net losses in the other, which also occurred in 1914, 1962, and 2022.[3] The 2018 election cycle was the first mid-term election cycle since 2002 in which any incumbents of the non-presidential party lost re-election. The number of defeated non-presidential party incumbents (4) was the most since the 1934 mid-terms.[4] As of 2023, this is the last time Republicans won control of the Senate, as well as the last time that the Democrats didn’t make net gains in the chamber.

Partisan composition

Among the 33 Class 1 Senate seats up for regular election in 2018, twenty-three were held by Democrats, two by independents who caucused with the Senate Democrats and eight by Republicans. Class Two seats in Minnesota and Mississippi held by interim appointees were also up for election; both incumbent appointees sought election to finish their unexpired terms.

Democrats targeted Republican-held Senate seats in Arizona (open seat) and Nevada.[5] Seats in Texas,[6] Mississippi (at least one of the two seats) and Tennessee (open seat)[7] were also competitive for the Democrats. Republicans targeted Democratic-held seats in Indiana, Missouri, Montana, North Dakota and West Virginia, all of which were won by Republicans in both the 2012 and 2016 presidential elections.[8] Seats in Florida, Ohio, Pennsylvania, Wisconsin and Michigan, all of which were won by Obama in 2008 and 2012 but by Trump in 2016, were also targeted by Republicans.[5][9] The Democratic-held seat in New Jersey was also considered unexpectedly competitive due to corruption allegations surrounding the Democratic incumbent.

The map was widely characterized as extremely unfavorable to Democrats, as Democrats were defending 26 states while Republicans were defending nine. Of these seats, Democrats were defending ten in states won by Donald Trump in the 2016 presidential election, while Republicans were only defending one seat in a state won by Hillary Clinton in 2016.[10][11][12] According to FiveThirtyEight, Democrats faced the most unfavorable Senate map in 2018 that any party has ever faced in any election.[13][14]

Change in composition

Each block represents one of the one hundred seats in the Senate. "D#" is a Democratic senator, "I#" is an Independent senator and "R#" is a Republican senator. Arranged so parties are separated and a majority is clear by crossing the middle.

Before the elections

Each block indicates an incumbent senator's actions going into the election. Some "Ran" for re-election, some "Retired," and those without a note were not up for election this cycle. Before the elections, Republicans held 51 seats, Democrats held 47, and Independents held 2.

After these elections, Democrats had 45 seats, independents had 2, and Republicans had 53.

Final pre-election predictions

Several sites and individuals publish predictions of competitive seats. These predictions look at factors such as the strength of the incumbent (if the incumbent is running for re-election) and the other candidates, and the state's partisan lean (reflected in part by the state's Cook Partisan Voting Index rating). The predictions assign ratings to each seat, indicating the predicted advantage that a party has in winning that seat.

Most election predictors used:

"tossup": no advantage
"tilt" (used by some predictors): advantage that is not quite as strong as "lean"
"lean": slight advantage
"likely" or "favored": significant, but surmountable, advantage
"safe" or "solid": near-certain chance of victory
