Woodrow Wilson Democratic Warren G. Harding Republican The 1920 United States presidential election in New Mexico took place on November 2, 1920.

During the period between New Mexico's annexation by the United States and statehood, the area was divided between largely Republican machine-run highland regions (which were a mix of Hispanos and Anglo migrants from the Midwest and Northeast) and its firmly Southern Democrat and Baptist "Little Texas" region to the southeast.

[1] A split in the "Old Guard" of highland Republicanism meant that in the state's inaugural presidential election in 1912 Woodrow Wilson carried the state through overwhelming "Little Texas" and southern desert support over Progressive Theodore Roosevelt and incumbent Republican William Howard Taft.

[2] Four years later in 1916, Wilson gained sufficient Progressive support to narrowly hold the state against Charles Evans Hughes and the reunited Republican Party; however, in 1918, despite extremely low turnout due to the Spanish flu epidemic[3] the reunited GOP regained considerable strength.

The corporate and "Old Guard" Republicans[2] campaigned on a "Return to Normalcy" following World War I and the tumult of the Bolshevik Revolution and attempts to spread it across Europe.
