1986 United States Senate elections

The 1986 United States Senate elections were elections for the United States Senate. Held on November 4, in the middle of Ronald Reagan's second presidential term, the 34 seats of Class 3 were contested in regular elections. The Republicans had to defend an unusually large number of freshman Senate incumbents who had been elected on President Ronald Reagan's coattails in 1980. Democrats won a net of eight seats, defeating seven freshman incumbents, picking up two Republican-held open seats, and regaining control of the Senate for the first time since January 1981. This remains the most recent midterm election cycle in which the sitting president's party suffered net losses while still flipping a Senate seat.

Democrats gained a net eight seats, and recaptured control of the Senate from the Republicans with a 55–45 majority. They defeated seven incumbents, all but one of whom had been elected in 1980, and gained open seats held by retiring Republicans in Maryland and Nevada. Republicans gained one open seat in Missouri. Bob Dole (R-Kansas) and Robert Byrd (D-West Virginia) exchanged positions as the Majority Leader and the Minority Leader. However, the Democratic majority would be reduced to 54-46 following the March 1987 death of Democrat Edward Zorinsky, who was then replaced with a Republican.

This was the last election cycle — until 2016 — in which the Democrats in this class of senators amassed a gain in seats (not including special elections held in off-years in some states to fill the seats that had been vacated by senators due to death, resignation, or otherwise).

Incumbent Republican Frank Murkowski ran for a second term and was primarily opposed by Democrat and Alaska Pacific University President Glenn Olds and Libertarian Chuck House, field representative for Eastman Kodak Company. Following a highly competitive election in 1980, Murkowski faced a legitimate opponent in Olds, and the contest was fairly close throughout the campaign. However, in the end, Murkowski was able to defeat Olds 63%-25% in the open primary. He won 54%-44% against Olds in the runoff.

Incumbent Republican Barry Goldwater decided to retire instead of seeking a sixth term. The open seat was won by Republican John McCain, a Congressman and former Navy Officer who beat Democratic State Legislator Richard Kimball. Both candidates were unopposed in their respective primaries.

Kimball's campaign was subject to negative press from the Arizona Republic and Phoenix Gazette. One Gazette columnist described him as displaying "terminal weirdness." McCain ultimately won the election by a margin of 20%, and he would go on to win six more terms to the U.S. Senate.

U.S. senator before election Charles Mathias Republican Elected U.S. Senator Barbara Mikulski Democratic

Incumbent Republican Charles Mathias decided to retire, instead of seeking a fourth term. At the time of this announcement, it was expected that then-Governor Harry Hughes would run for the seat being vacated by retiring Senator Mathias. However, Hughes became caught up in the aftermath of the Maryland savings and loan crisis. He lost popularity with voters, opening the door for Mikulski's bid for the Senate. Congresswoman Barbara Mikulski received the Democratic nomination over fellow Congressman Michael D. Barnes and governor Harry Hughes, the last of whom finished third. Mikulski had previously run for the seat in 1974.

Chavez won the primary handily, defeating several Republican challengers. Later, she made comments that some Mikulski supporters interpreted as an attempt to draw attention to the issue of Mikulski's sexual orientation. In an article quoting Chavez's claim that Mikulski was a "San Francisco-style, George McGovern, liberal Democrat", The Washington Post reported that Chavez was directly implying that the never-married Mikulski was a lesbian. Chavez was accused of making Mikulski's sexual orientation a central issue of the political campaign. In defending her use of the phrase, Chavez stated the line "San Francisco Democrats" was a reference to Jeane Kirkpatrick's 1984 Republican National Convention "Blame America First" speech, in which Kirkpatrick coined the phrase "San Francisco Liberal.". The phrase "San Francisco liberal" was common at the time.

Mikulski eventually won the race with 61 percent of the vote. She was the first female Democrat elected to the U.S. Senate in her own right (not appointed or filling a seat of a deceased husband). No Republican since Mathias has represented Maryland in the U.S. Senate.

Main article: 1986 United States Senate elections in North Carolina

There were two elections in North Carolina.

Incumbent Republican Jim Broyhill, who had been appointed in June 1986 to serve out the rest of John Porter East's term, faced off against the popular Democratic former Governor Terry Sanford. There were two separate elections held on the same day: a special election for what little remained of the 99th United States Congress (November 1986 – January 1987) and a regular election for a new six-year term (beginning in January 1987). Sanford won both elections.

The primary elections would nominate candidates to the special and the regular election.

U.S. senator before election Jim Broyhill Republican Elected U.S. Senator Terry Sanford Democratic

Terry Sanford, then the outgoing president of Duke University, first said in September 1985 that he was planning to run for the U.S. Senate the next year but quickly withdrew, as it appeared that the party wanted a "fresh" face, most likely in the person of UNC System President William Friday. Then, Friday declined to run, as did other well-known politicians like former Gov. Jim Hunt. Former North Carolina Secretary of Commerce Lauch Faircloth then made it known that he would run, but he was considered too conservative by many party leaders, who encouraged Sanford to enter the race in order to defeat Faircloth. Sanford agreed to run, which led Faircloth and another candidate, Judge Marvin K. Blount Jr., to withdraw before filing their candidacies. Six years later, Faircloth did run for the Senate against Sanford, but this time as a Republican.

Sen. East declined to run for a second term, citing his health. Longtime U.S. Representative Jim Broyhill entered the race with much of the establishment support, but David Funderburk had the backing of the organization of Senator Jesse Helms. Funderburk charged Broyhill with being insufficiently conservative, but in the end, Broyhill won the nomination handily in the May primary. The next month, Sen. East committed suicide, and Gov. James G. Martin appointed Broyhill to his seat.

Sanford narrowly defeated incumbent Broyhill on both election ballots, though he received a slightly smaller margin of victory to finish the remainder of East's term due to a lower turnout.

Incumbent Bob Packwood ran for re-election, though he faced a significant primary challenge from Joe Lutz. U.S. Congressman Jim Weaver received the Democratic nomination. A populist Democratic congressman from Eugene, Oregon, he was a darling of the environmentalists. Weaver supported the Oregon Wilderness Act of 1984. Packwood was confident despite the popular opponent, because had more money and a better campaign organization. After winning the party nomination, Weaver was the subject of a House Ethics Committee probe into his campaign finances, and withdrew his candidacy. Rick Bauman was selected to replace Weaver on the ballot, and lost handily to Packwood.

Incumbent Republican Arlen Specter, who had been elected in 1980, ran for re-election and faced Democrat Robert W. Edgar in the general election.

Specter was viewed somewhat tepidly by the Pennsylvania electorate entering the race, although both men shared similar moderate profiles. Additionally, economic woes had dragged down the popularity of Republican candidates in the industrial states. Don Bailey, the state's incumbent Auditor General, who projected a strong blue collar image and had moderate positions that were often relatively close to Specter's, and Edgar, a Methodist minister and sitting Congressman, who had more liberal viewpoints and was with the Vietnam War-era peace movement and anti-corruption movement following the Watergate scandals, ran for the Democratic nomination. However, issues played a very minor role in the primary, which instead showcased the state's geographical divide, with Delaware County-based Edgar narrowly defeating Westmoreland County-based Bailey.

Specter defeated Edgar in the general election by nearly 13% of the vote.

Popular incumbent Democratic Senator Fritz Hollings easily defeated Republican U.S. Attorney and future Governor Henry McMaster, who defeated Henry Jordan for the Republican nomination, to win his fifth (his fourth full) term.

The race was not seriously contested and was not a target by the Republicans. With little financial assistance, McMaster was unable to mount a credible challenge to Hollings's re-election in what became a difficult year for Republicans.

Incumbent Republican James Abdnor ran for re-election to a second term, but was defeated by Democratic Congressman Tom Daschle.

Incumbent Democrat Patrick Leahy won re-election to a third term over Republican former Governor of Vermont Richard A. Snelling and Liberty Unionist sociologist and perennial candidate Jerry Levy. The race was initially expected to be competitive, with Ronald Reagan encouraging Snelling to run.

Both Leahy and Snelling were well-respected and highly popular in Vermont, and the general feeling was that they would both make good senators. However, Snelling was felt to be at a disadvantage for several reasons, including the fact that his main campaign plank was deficit reduction, which The Caledonian-Record noted Leahy was already a well-known advocate for, and the fact that Leahy had acquired a reputation as one of the Senate's most knowledgeable figures on the issue of nuclear proliferation, an issue which the Brattleboro Reformer noted that Snelling had no experience with.

Nonetheless, Leahy defeated Snelling in a 63%-35% landslide. Leahy would face one more tough re-election challenge in 1992 against Republican Jim Douglas, handily winning each term thereafter.
