The 1990 United States Senate elections were held on Tuesday, November 6, 1990, with the 33 seats of Class 2 contested in regular elections. Special elections were also held to fill vacancies. The Democratic Party increased its majority with a net gain of one seat from the Republican Party. The election cycle took place in the middle of President George H. W. Bush's term, and as with most other midterm elections, the party not holding the presidency gained seats in Congress. This was the first time since 1980 that any party successfully defended all their own seats, and the first time Democrats did so since 1958.

These elections, along with 2022, featured the smallest seat change in history since the passage of the Seventeenth Amendment in 1913, with only one seat changing parties. This election featured Democrat Paul Wellstone defeating incumbent Republican Rudy Boschwitz in Minnesota. To date, this is the last cycle in which Democratic candidates won U.S. Senate elections in Oklahoma and Tennessee.

Background

The election was held as part of the midterm election cycle of Republican President George H. W. Bush's term. Historically, the President's party struggles during the midterms.

Incumbent Democratic Joe Biden won re-election to a fourth term, defeating Republican challenger Deputy Attorney General of Delaware M. Jane Brady. Brady decided to run because she felt that Biden's liberal voting record did not reflect the political positions of Delawareans. The election had a turnout rate of under 40% of registered voters. Biden won in a landslide with over 60% of the vote improving on his 1984 margin, winning all three counties and all 41 state house districts.

Indiana (special)

Incumbent Republican Dan Coats, who was recently appointed to this seat two years prior, won election to serve out the remainder of the term, beating Democratic State Representative Baron Hill.

During the 1988 presidential election, Republican nominee Vice President George H. W. Bush selected U.S. Senator Dan Quayle of Indiana as his vice presidential nominee. The Bush-Quayle ticket defeated the DukakisBentsen ticket in the general election by a 53%-46% margin, capturing 40 states and 426 electoral votes.

In preparation for the pending vacancy, Governor Robert D. Orr appointed four-term U.S. Representative Dan Coats to fill Quayle's seat on December 12, 1988. Coats was a former aide to Quayle, whom he had succeeded as U.S. Representative for Indiana's 4th congressional district in 1981. Quayle eventually resigned his Senate seat on January 3, 1989, and Coats was immediately sworn into office.

Coats used television commercials that raised questions about Hill's consistency in opposing new taxes, and Hill gained notoriety for walking the length of the state to meet voters.

Louisiana

Incumbent Democrat J. Bennett Johnston Jr. won re-election to a fourth term and avoided a runoff, beating Republican David Duke, State Representative and former Grand Wizard of the Ku Klux Klan.

This election was viewed at the onset as potentially competitive, as Senator Johnston was viewed as vulnerable in light of Louisiana's economic troubles at the time and Senator Johnston's voting record viewed by Republicans as too liberal. The Republican Party leadership endorsed the candidacy of State Senator Ben Bagert, who was picked over Secretary of State Fox McKeithen, State Representative Quentin Dastugue and State Representative David Duke. David Duke, however, continued his candidacy and slowly overtook Bagert in attention and in the polls. Duke attracted national attention to the race with his involvement with white supremacist groups and his appeals to white resentment over affirmative-action programs. With Bagert failing to gain traction, the National Republican Senatorial Committee tried to recruit former Governor David Treen to jump into the race. When Treen passed, the effort turned from supporting Bagert to stopping Duke.

As the election drew near, polls showed Johnston firmly in first place, with Duke in second place and Bagert trailing far behind at third. National Republicans grew fearful that Bagert's candidacy would only serve to force a runoff and that a potential runoff election with Duke being the de facto Republican nominee would hurt the national brand. On October 4, eight Republican Senators endorsed Johnston, with Senator John Danforth saying at the press conference that "all of us would be embarrassed and mortified to have to serve in the United States Senate with David Duke masquerading as a Republican." Bagert dropped out of the race the next day, announcing that "it became more and more apparent, that instead of forcing a runoff between myself and Bennett Johnston, I might very well be forcing a runoff between somebody else and Bennett Johnston." He announced he would "reluctantly" vote for Johnston. Bagert's name remained on the ballot, but under state law his votes could not be counted as part of the official tally. After Bagert dropped out, HUD Secretary Jack Kemp endorsed Johnston, saying "there's no place in the Republican Party for someone who has practiced and practices racism, bigotry and anti-Semitism."

New Jersey

Democratic Senator Bill Bradley decided to seek re-election and narrowly edged out little-known Republican Christine Todd Whitman, President of the New Jersey Board of Public Utilities.

Senator Bill Bradley didn't realize he was in trouble of winning re-election and the New Jersey voters' anger over taxes and economy until the week prior to the election.

The senator had a major image problem. In the early part of the campaign Bradley was winning easily in the polls, so his staffers told him to play it safe. He sent out television advertisements of himself walking on the beach, shooting a perfect shot on the court, and sitting back in his office with his basketball shoes onto his desk. The advertisements backfired as voters were turned off and thought that he hadn't taken his job as Senator seriously, at a time when New Jersey voters were suffering.

Another major problem with Bradley was how Democratic Governor Jim Florio implemented a $2.8 billion tax increase, hurting the state's economy. In addition, Bradley refused to answer questions pertaining to Florio's tax policies.

After Bradley realized he was in trouble he released negative advertisements. They attacked Whitman's own record on taxes, accusing her of favoring tax increases when she was a Somerset County Freeholder. Bradley's image may have been further damaged by his newer advertisements.

North Carolina

The election was fought between the Republican incumbent Jesse Helms and the Democratic nominee Mayor of Charlotte Harvey Gantt. Helms won re-election to a fourth term by a slightly wider margin than the close election in 1984.

Helms drew controversy for airing what became known as the "Hands" ad produced by Alex Castellanos. It showed a pair of white hands with the voiceover saying "You needed that job, and you were the best qualified. But they had to give it to a minority because of a racial quota." The ad prompted allegations of racism.

Oregon

Republican Mark Hatfield was re-elected to a fifth term, defeating Democratic businessman Harry Lonsdale. Hatfield faced minimal opposition in the Republican primary, his only major competition was from environmentalist and former Eugene, Oregon mayoral candidate Randy Prince. Hatfield easily defeated Prince receiving nearly eighty percent of the vote. Lonsdale, who had founded the biotechnology company Bend Research, announced in early 1990 that he intended to challenge Hatfield over his ties to special interest groups, and his opposition to abortion rights. During the primary, Lonsdale largely ignored his Democratic opposition opting to directly criticize Hattfield. Despite close polling, Hatfield won all but four counties and won the popular vote by over seven points.

South Carolina

Popular incumbent Republican Strom Thurmond cruised to re-election against Democratic challenger and perennial candidate Bob Cunningham.

Senator Strom Thurmond faced no opposition from South Carolina Republicans and avoided a primary election. The state Democrats saw this as an unwinnable race so when Bob Cunningham sought the Democratic nomination, he was unopposed in his bid.

Cunningham launched his second bid to unseat Republican Sen. Strom Thurmond after switching from the GOP to the Democratic Party in early 1990. Though he faced a formidable opponent, Cunningham planned no fund-raising activities. "I don't plan to ask for anything and I won't accept any money from PACs", he said. Cunninghman said his campaign strategy was to "go to places where I was invited and spread out my ideas." If elected, Cummingham said he would push to limit consecutive congressional service to 12 years and reform the tax system. He supported greater environmental activism. "I think we're going at it in much too lukewarm a fashion. I think we should work hard to find a substitute for the internal combustion engine."

The election was never a serious contest. Thurmond overwhelmingly outspent Cunningham in his re-election campaign.
