The 1972 United States Senate elections were held on November 7, with the 33 seats of Class 2 contested in regular elections. They coincided with the landslide re-election of Republican President Richard Nixon. Despite Nixon's landslide victory, Democrats increased their majority by two seats. The Democrats picked up open seats in Kentucky and South Dakota, and defeated four incumbent senators: Gordon Allott of Colorado, J. Caleb Boggs of Delaware, Jack Miller of Iowa, and Margaret Chase Smith of Maine. The Republicans picked up open seats in New Mexico, North Carolina, and Oklahoma, and defeated one incumbent, William B. Spong Jr. of Virginia.

Contents

After the elections, Democrats held 56 seats, and Republicans held 42 seats, with 1 Conservative and 1 independent senator in the chamber as well. These were the first elections in which all citizens at least 18 years of age (instead of 21, and older) could vote, due to the 1971 passage of the 26th Amendment.

As of 2024, this is the last time in which a Republican won a Senate election in New Jersey. Joe Biden, the 46th president of the United States (2021–present) and 47th vice president (2009–2017), first won election to the United States Senate, defeating J. Caleb Boggs in the election in Delaware.

Elected U.S. Senator

John Sparkman
Democratic

In 1946, John H. Bankhead II suffered a stroke during a U.S. Senate hearing and died three weeks later. John Sparkman, who had served as U.S. Representative since 1937 and was House Majority Whip, secured the endorsements of party leaders and ran unopposed to win the remainder of Bankhead's term. Sparkman was then re-elected in 1948, 1954, 1960, and 1966 all by wide margins. At the time, the Democratic Party was dominant in Alabama; winning the Democratic primary virtually guaranteed a general election victory. Until 1966, Sparkman never faced an opponent in the general election who garnered more than 30% of the vote. Sparkman also served as the running mate of Adlai Stevenson II in an unsuccessful 1952 presidential campaign.

However, in 1966, the Democratic Party began to feel the backlash of Civil rights legislation in the South, and Sparkman faced his closest political contest to date. He defeated John Grenier with just 60% of the vote. Richard Nixon's election in 1968 also helped Republicans gain recognition in Alabama. In 1972, Sparkman faced Winton M. Blount, who was serving as Postmaster General. [4]

Sparkman ultimately increased his vote share in a lopsided victory over Blount, who won just two counties, Houston county and, fittingly, the phonetically similar Winston county. This would be Sparkman's final term as U.S. senator. He retired in 1979 and was succeeded by Howell Heflin.

Republican Ted Stevens was originally elected to the U.S. Senate in 1970, succeeding Democrat Bob Bartlett. He won election to the remainder of Barlett's term with nearly 60% of the vote.

In 1972, he faced Democrat Gene Guess in the general election. Stevens won re-election in a landslide even as Democrat Mike Gravel served as the state's other senator. On election day, Stevens won re-election to a second term (his first full term) against Guess, 77–23%. Stevens would be re-elected in 1978, 1984, 1990, 1996, and 2002 with at least 66% of the vote before losing re-election in 2008 amid criminal charges.

Joe Biden
Democratic

Incumbent Republican J. Caleb Boggs, running for a third term, faced off against future President Joe Biden, then a New Castle County Councilman. Though Boggs was expected to easily win a third term over the then-unknown Biden, it ended up being the closest Senate election in 1972, and Biden narrowly beat out Boggs by a little over three thousand votes, winning what would be his first of seven terms.

Boggs, a longtime Delaware political figure, was considering retirement which would likely have led to a primary campaign between two Republicans, U.S. Representative Pete du Pont and Wilmington Mayor Harry G. Haskell Jr. To avoid the anticipated divisive primary fight, U.S. President Richard M. Nixon helped convince Boggs to run again with full party support.

No other Democrat wanted to run against Boggs besides Biden. [6] Biden's campaign had virtually no money and was given no chance of winning. [7] It was managed by his sister Valerie Biden Owens (who would go on to manage his future campaigns as well) and staffed by other members of his family, and relied upon handed-out newsprint position papers. [8] Biden did receive some assistance from the AFL–CIO and Democratic pollster Patrick Caddell. [6] Biden's campaign issues focused on withdrawal from Vietnam, the environment, civil rights, mass transit, more equitable taxation, health care, the public's dissatisfaction with politics-as-usual, and "change". [6] [8]

During the summer Biden trailed by almost 30 percentage points, [6] but his energetic campaign, his attractive young family, and his ability to connect with voters' emotions gave the surging Biden an advantage over the ready-to-retire Boggs. [9] Biden won the November 7, 1972, election in an upset by a margin of 3,162 votes. [8]

At the time of the election Biden was a little less than 30 years old; age 30 is a constitutional requirement for the U.S. Senate, and he reached that on November 20, in time for the Senate term beginning January 3. After his election he became the sixth-youngest senator in history. [10]

Georgia

Seven-term Democrat Richard Russell Jr. had served as U.S. senator since 1933, but he died January 21, 1971, while serving as President pro tempore. Russell supported segregation in the South and opposed Civil Rights legislation as was common among Southern Democrats of the time. Governor of Georgia Jimmy Carter appointed Democrat David H. Gambrell, the chair of the Georgia Democratic Party as interim senator, pending a special election.

Sam Nunn
Democratic

Sam Nunn, a Democratic member of the Georgia House of Representatives, won both the special and the regular elections. Nunn beat Gambrell in the August 29 special and regular primary run-off elections [11] despite trailing Gambrell initially 31-23% in the first round of voting.

In the special election to fill the remainder of Russell's term, Nunn faced Republican congressman Fletcher Thompson. Nunn's campaign was noted to be more organized than was Thompson's. Nunn had support from numerous prominent Georgia Democrats, including Gambrell and Carter. Thompson's campaign was "almost literally a one-man effort", and he started the race with almost no footprint outside of his own district. [12] Thompson was endorsed by Barry Goldwater, James L. Buckley, and Spiro Agnew. [13]

On the day of the special election, Nunn defeated Thompson 52-47%. Though Thompson performed well in the Atlanta metro area, Nunn swept most rural counties en route to a victory.

Sam Nunn
Democratic

In the general election held later that year, Nunn again defeated Thompson this time by almost 8 percentage points. Nonetheless, this marked a turning point in Georgia electoral politics: Nunn became the first Democrat to win a Senate race in Georgia despite losing the white vote. [12] Nunn also proved to be more moderate than his predecessor Russell, voting in favor of abortion rights, gun control, affirmative action, and environmental regulations.

Nunn would be re-elected in 1978, 1984, and 1990 before retiring in 1997. This was the last time he won less than 79% of the vote in a U.S. Senate election. In 1996, he was succeeded by Democrat Max Cleland.

Louisiana

In the midst of his campaign for a seventh term, Allen J. Ellender, the President Pro Tempore and chairman of the Appropriations Committee, suffered a fatal heart attack on July 27, 23 days prior to the Democratic primary. Ellender, first elected in 1936 as the permanent successor to the assassinated Huey P. Long, was slated to face former state senator and 1971 gubernatorial candidate J. Bennett Johnston and minor candidate Frank Allen in the primary.

Governor Edwin Washington Edwards, who defeated Johnston by less than 4,500 votes in the 1971 Democratic runoff, nominated his wife, Elaine Edwards, to fill the remainder of Ellender's term, with the agreement Mrs. Edwards would resign immediately following the general election to allow the winner to gain seniority over other new senators.

On the same day as Edwards' inauguration on Capitol Hill, the Louisiana Democratic Party rejected a challenge by former Governor John McKeithen to reopen qualifying following Ellender's death, ordering the primary to be held August 19 as scheduled, ignoring an opinion to the contrary by Louisiana Attorney General William J. Guste Jr. Ellender's name was not removed from the ballot and he received 10 percent of the primary vote as a tribute. McKeithen, whose eight-year gubernatorial tenure ended May 9, 1972, ran as an independent with support of the Ellender family, incensed by Johnston's primary challenge.

Johnston easily won the Democratic primary, nullifying the need for a September 30 runoff. In the general election, the Shreveport native trounced McKeithen by 32 points to win the first of his four terms. He was sworn in on November 13, 1972.

<span class="mw-page-title-main">1910–11 United States Senate elections</span>

The 1910–11 United States Senate election were held on various dates in various states. As these U.S. Senate elections were prior to the ratification of the Seventeenth Amendment in 1913, senators were primarily chosen by state legislatures. Senators were elected over a wide range of time throughout 1910 and 1911, and a seat may have been filled months late or remained vacant due to legislative deadlock. However, some states had already begun direct elections during this time. Oregon pioneered direct election and experimented with different measures over several years until it succeeded in 1907. Soon after, Nebraska followed suit and laid the foundation for other states to adopt measures reflecting the people's will. By 1912, as many as 29 states elected senators either as nominees of their party's primary or in conjunction with a general election.

Though Boggs was expected to easily win a third term, Biden narrowly defeated the incumbent on election day, even while fellow Democrat George McGovern lost Delaware by 20.4% in the concurrent presidential election.

<span class="mw-page-title-main">1972 United States Senate elections in Georgia</span>

The 1972 United States Senate election in Georgia took place on November 7, 1972, as one of that year's United States Senate elections. It was held concurrently with the 1972 presidential election. This seat had opened up following the death of Richard B. Russell in 1971. Shortly thereafter, Governor of Georgia Jimmy Carter appointed David H. Gambrell to fill Russell's vacant seat. The Democratic Party nominee was Sam Nunn, a conservative Democrat and member of the Georgia House of Representatives, and the Republican Party nominated Fletcher Thompson, the Representative from the Atlanta-area 5th congressional district of Georgia. In the primary, Nunn emerged victorious from a crowded field of Democratic candidates, including Gambrell and former Georgia Governor Ernest Vandiver. Despite President Richard Nixon defeating George McGovern in Georgia in the presidential election on the same day, Nunn defeated Thompson in both the special election 52% to 47% and general election 54% to 46%, both of which appeared on the same ballot.
