The 1964 United States Senate elections were held on November 3. The 33 seats of Class 1 were contested in regular elections. Special elections were also held to fill vacancies. They coincided with the election of President Lyndon B. Johnson by an overwhelming majority, to a full term. His Democratic Party picked up a net two seats from the Republicans. As of 2023, this was the last time either party has had a two-thirds majority in the Senate, which allowed the Senate Democrats to override a veto, propose constitutional amendments, or convict and expel certain officials without any votes from Senate Republicans. However, internal divisions would have prevented the Democrats from having done so. The Senate election cycle coincided with Democratic gains in the House in the same year.

In a close race in Nevada, Democratic incumbent Howard Cannon won re-election over Republican Lieutenant Governor Paul Laxalt by fewer than 100 votes. Laxalt joined Cannon in the Senate when he won Nevada's other seat in 1974. Patrick V. McNamara (D–Michigan) later died on April 30, 1966, and was replaced on May 11, 1966, by appointee Robert P. Griffin (R), reducing Democrats' majority to 67–33.

Notably, of the 35 seats up for election this year, 26 were held by Democrats, who managed to retain 25 of them. A party defending two-thirds of the seats up for election would not make net gains in the Senate again until 2012. Coincidentally, it would be the same Senate class, class 1. This is the earliest round of Senate elections in which a first-elected member is still alive (Fred Harris, D-OK).

Paul Fannin
Republican

Incumbent Barry Goldwater decided not to run for re-election to a third term, instead running for President of the United States as the Republican Party nominee against Lyndon B. Johnson.[2] Governor of Arizona Paul Fannin ran unopposed in the Republican primary, and defeated Democratic nominee Roy Elson, who was a staff member for U.S. senator Carl Hayden until Hayden's retirement in 1969. Despite a landslide loss throughout the country, and Goldwater only able to obtain 50.45% of the vote in his home state of Arizona, Fannin managed to prevail in the state's Senate election. Goldwater would win the election for the other Senate seat in 1968 when Hayden retired from the post and serving two more terms.

Incumbent Republican U.S. Senator Kenneth Keating ran for re-election to a second term, but was defeated by Robert F. Kennedy, the former United States Attorney General and brother of former President John F. Kennedy and Massachusetts Senator Ted Kennedy.

The Socialist Labor state convention met on March 29, and nominated John Emanuel.[15] The Republican state convention met on August 31, and re-nominated the incumbent U.S. Senator Kenneth B. Keating.[16] The Conservative state convention met on August 31 at Saratoga Springs, New York, and nominated Prof. Henry Paolucci.[17] The Democratic state convention met on September 1, and nominated U.S. Attorney General Robert F. Kennedy on the first ballot, with 968 votes against 153 for Congressman Samuel S. Stratton.[18] The Liberal Party met on September 1, and endorsed the Democratic nominee, U.S. Attorney General Robert F. Kennedy.[19] The Socialist Workers Party filed a petition to nominate candidates on September 7. Richard Garza was nominated.[20]

John English, a Nassau County leader who helped John F. Kennedy during the 1960 presidential election, encouraged Robert Kennedy to oppose Keating. At the time, Samuel S. Stratton, a member of the United States House of Representatives from New York's 35th congressional district, was considered the most likely Democratic candidate. At first, Kennedy resisted. After President Kennedy's assassination, Robert Kennedy remained as Attorney General for Lyndon B. Johnson. However, Johnson and Kennedy feuded. Kennedy decided to run for the Senate in New York in August, and resigned from the Cabinet on September 3, 1964. While many reform Democrats resisted Kennedy, support from Robert F. Wagner Jr., and party bosses like Charles A. Buckley, of The Bronx, and Peter J. Crotty,[d] of Buffalo, helped Kennedy win the nomination at the party convention.[22]

During the campaign, Kennedy was frequently met by large crowds. Keating accused Kennedy of being a carpetbagger from Massachusetts. Kennedy responded to these charges in a televised town meeting by saying, "If the senator of the state of New York is going be selected on who's lived here the longest, then I think people are going vote for my opponent. If it's going be selected on who's got the best New York accent, then I think I'm probably out too. But I think if it's going be selected on the basis of who can make the best United States senator, I think I'm still in the contest."[23]

The Democratic/Liberal candidate was elected. Campaign help from President Lyndon B. Johnson, as well as the Democratic landslide after the assassination of John F. Kennedy, helped carry Kennedy into office, as Kennedy polled about 1.1 million votes less in New York than Johnson did. The incumbent Keating was defeated.
