Nixon took 63.98% of the vote to McGovern's 34.85%, a margin of 29.12%. New Hampshire in this era normally leaned Republican, having not gone Democratic since the nationwide Democratic landslide of 1964. As Nixon won re-election nationally in a 49-state landslide, New Hampshire easily remained in the Republican column, with McGovern's only victories coming from neighboring Massachusetts and the District of Columbia.
On the county map, Nixon swept all 10 of the state's counties, breaking 60% in 7 of them. As in previous elections, Carroll County and Belknap County were the most Republican counties in the state, both voting over 70% for Nixon. McGovern's strongest county was Strafford County, where he managed 41.3% of the vote to Nixon's 57.8%.
Amidst Nixon's landslide nationwide win, New Hampshire would weigh in as almost 6% more Republican than the national average, and would be the most Republican state in the Northeast. Nixon had previously won New Hampshire in both 1960 and 1968.
