United States presidential election in New Hampshire, 1964

The 1964 United States presidential election in New Hampshire took place on November 5, 1964 as part of the 1964 United States presidential election, which was held throughout all 50 states and D.C. Voters chose four representatives, or electors to the Electoral College, who voted for President and Vice President.

New Hampshire was won overwhelmingly by the Democratic nominees, incumbent President Lyndon B. Johnson of Texas and his running mate Senator Hubert H. Humphrey of Minnesota. Johnson and Humphrey defeated the Republican nominees, Senator Barry Goldwater of Arizona and his running mate Congressman William E. Miller of New York.

Johnson took 63.89 percent of the vote to Goldwater’s 36.11 perccent, a margin of 27.78 percent.

The staunch conservative Barry Goldwater was widely perceived in the liberal Northeastern United States as a right-wing extremist; he had voted against the Civil Rights Act of 1964, and the Johnson campaign portrayed him as a warmonger who as president would provoke a nuclear war. Thus Goldwater performed especially weakly in liberal northeastern states like New Hampshire, and for the first time in history, a Democratic presidential candidate swept every Northeastern state in 1964. Not only did Johnson win every Northeastern state, but he won all of them with landslides of over sixty percent of the vote, including New Hampshire.

Despite the scale of Johnson’s statewide win, he did not sweep every county in New Hampshire. Carroll County had long been the most Republican county in New Hampshire, voting over seventy percent Republican in 1960 and over eighty percent Republican in 1952 and 1956. In 1964, Carroll County would again be the most Republican county in the state, voting 55-45 Goldwater even as every other county in the state voted decisively for Johnson. In 1964, Carroll County was not only the only county carried by Goldwater in New Hampshire, it was the only county Goldwater won in all of the Northeastern United States outside of Pennsylvania. Despite the landslide loss, New Hampshire would prove to be Goldwater's strongest state in the Northeast.

Johnson won the remainder of the state by decisive margins, with his strongest victories in the New Deal Democratic base counties of Hillsborough County, Strafford County, and Coos County, which had long been Democratic counties in an otherwise Republican state, even as the rest of the state finally joined them in voting Democratic in 1964. His strongest victory was in rural Coos County in the far north of the state, which Johnson won with 71.1% of the vote.

As Johnson won a decisive nationwide landslide with 61.05% of the vote, normally Republican-leaning New Hampshire's results made the state over 5% more Democratic than the national average in the 1964 election.
