As Johnson won nationally in a massive landslide, taking 61.05% of the vote nationwide, and dominating many Northeastern and Midwestern states by record landslide margins, California actually weighed in as about 4% more Republican than the national average in the 1964 election. Johnson dominated in more liberal Northern California, breaking 60% in many counties and even breaking 70% in Plumas County and the city of San Francisco. However the Western Conservative Goldwater, from neighboring Arizona, did hold some appeal in Southern California, where Johnson failed to break 60% in a single county and Goldwater even won two heavily populated Southern California counties, Orange County, and San Diego County, holding Johnson below the 60% mark statewide.
Although California has become a strongly Democrat state in recent elections, this was the only presidential election between 1952 and 1992 where the state was carried by a Democrat. Johnson is also the last Democrat to carry the counties of Calaveras, Colusa, Glenn, Inyo, Kern, Modoc and Tulare, and the last to win the majority of the vote in Butte, El Dorado, Kings, Mariposa, Siskiyou and Tuolumne counties (Although some Democrats since have won a plurality in those counties).
