1964 New Mexico gubernatorial election

The 1964 New Mexico gubernatorial election took place on November 3, 1964, in order to elect the Governor of New Mexico. Incumbent Democrat Jack M. Campbell ran for reelection to a second term against Republican Merle H. Tucker. Campbell defeated Tucker in a landslide, receiving the largest share of the vote by any New Mexico gubernatorial candidate to that point. Campbell's 60.21% vote share remained the largest ever in the state's history until 2006 when Bill Richardson received 68.82% of the vote. Richardson's 2006 landslide is also the only time since this election that Chaves County and San Juan County have voted for a Democratic gubernatorial candidate and Los Alamos County also did not vote Democratic again until 2006.
