United States gubernatorial elections were held on 3 November 1970, in 35 states and two territories.
During this election, the Democrats won a number of the governorships up for re-election via many ways, such as retirement of an incumbent, term limits, or the defeat of incumbent.
In 1970, Arizona, New Mexico and Wisconsin elected their governors to four-year terms for the first time, having previously elected them to two-year terms.
This election coincided with the Senate and the House elections.
Alabama
In Alabama, Governor Albert Brewer (who succeeded to the governorship upon Lurleen Wallace's death in 1968) had to endure a very nasty Democratic primary against former Governor George Wallace. In addition, there were no Republicans in the race for governor. Wallace won the Democratic primary and in November the election.
Alaska
In Alaska, then-Lt. Gov. Keith Miller had gotten the job of governor in 1969 after Walter Hickel resigned to be part of President Nixon's Cabinet. He lost in 1970 to former Governor William Egan.
Arizona
In Arizona, governors were elected to serve two-year terms until 1970, when Jack Richard Williams was the first governor to be elected to a four-year term. Previously, Williams had been elected governor twice to two-year terms in 1966 and in 1968. Arizona made the switch official from a two-year term to a four-year term in 1968 with an amendment.
Arkansas
In Arkansas, Winthrop Rockefeller was the first Republican governor in Arkansas since the Reconstruction period. He was defeated in his bid for a third term, by the Democratic challenger Dale Bumpers.
California
Incumbent Republican Governor and future President Ronald Reagan was elected to a second term as governor with about 53% of the vote over Speaker of the State Assembly Jesse Unruh.
Connecticut
Incumbent John Dempsey, a Democrat, did not seek re-election. Sixth District Congressman Thomas Joseph Meskill (Republican) defeated First District Congressman Emilio Q. Daddario (Democratic) 53.76% to 46.23%.
Colorado
In Colorado, John Arthur Love won re-election. He served until 1973, when he would resign to become the first head of Energy Policy under President Nixon.
Florida
Florida's Claude R. Kirk Jr. was another 'first Republican governor since Reconstruction' as well (he switched from Democrat to Republican early on), and was defeated by the Democrat Reubin Askew.
Georgia
In Georgia, governors would be limited to one term until George Busbee was allowed to serve two, and was the first governor to serve two consecutive terms. Future president Jimmy Carter won the election.
Hawaii
In Hawaii, Burns won another term in 1970, but in 1973, Burns had health problems and his Lt. Governor George Ariyoshi, took over-as acting governor, and in 1974, with Burns' retirement, won a term in his own right. Burns died in 1975.
Iowa
Iowa also had its governors serving two-year terms until Robert D. Ray won a four-year term in 1974. Previously, Ray had won a two-year term in 1968, a two-year term this year (1970), and would win another two-year term in 1972. Iowa made the four-year term switch official with an amendment to the state's constitution in 1972.
Kansas
Like Arizona and Iowa, Kansas also had its governors serving two-year terms until 1974, when a constitutional amendment was added, creating a four-year term system for governors. Docking was elected governor in 1966, 1968, 1970, and would get elected in 1972. The first governor to get a four-year term was Robert Frederick Bennett in 1974.
Maine
Beginning with the 1962 governor's race, Maine switched from a two-year term system to a four-year term system for the governors. John H. Reed was the first Maine governor to be elected to a four-year term. Kenneth Curtis was re-elected.
Maryland
In Maryland, Mandel first won the governorship in 1969 in a special election when Agnew resigned in order to become vice president.
In 1970, Mandel ran for a full term and won.
Massachusetts
In 1966, Massachusetts switched from a two-year to four-year terms for governors, and John A. Volpe was the first Massachusetts governor to be elected to a four-year term. He had previously been elected to two-year terms in 1960 and in 1964. Volpe resigned in 1969 to become President Nixon's Secretary of Transportation. Francis W. Sargent then became acting governor. In 1970, Sargent got a term in his own right.
