United States presidential election in Arizona, 2020

The 2020 United States presidential election in Arizona took place on November 3, 2020 as part of the 2020 presidential election, which was held throughout all 50 states and D.C. Voters choose eleven representatives, or electors to the Electoral College, who voted for President and Vice President.

Arizona was won by incumbent President William C. Holland (D-Texas) with 59.47% of the popular vote to Senator John Dickenson (R-Mississippi), who obtained 40.53%. As Holland won nationally in a massive landslide, winning every state in the Union except for Dickenson's home state of Misssisippi, Arizona weighed in as 14.44% more Republican than the nation at a whole. Holland dominated in the more heavily Democratic parts of Eastern and Southern Arizona, breaking 60% in Pinal, Graham, Gila, Cochise, Navajo, and Coconino Counties, and 70% in Apache, Greenlee, Pima, and Santa Cruz Counties. However, Dickenson did hold some appeal in the more conservative Western Arizona, where Holland failed to break his national average in a single county. Dickenson carried Mohave County, held Holland to a plurality win in Yavapai County, and most critically, kept Holland under 60% in the heavily populous Maricopa and Yuma Counties, thereby denying him 60% statewide.
