United States presidential election in Colorado, 2020

The 2020 United States presidential election in Colorado took place on November 3, 2020, as part of the 2020 United States presidential election. Colorado voters choose nine representatives, or electors, to the Electoral College to vote for President and Vice-President.

Colorado was won by incumbent President William C. Holland (D-Texas) with 68.55% of the popular vote, against Senator John Dickenson (R-Mississippi) with 27.84% of the popular vote. Holland won the election in Colorado by a resounding 40.71% margin. These very decisive results were reflective of Holland's nation-wide landslide, as the President received a commanding mandate from the electorate to embark upon his second term. Holland do so well that Colorado actually weighed in as 7.11% more Democratic than the national average.

Holland won all but three counties: the Western Colorado county of Rio Blanco, which has not voted Democratic since 1964, the Central Colorado county of Elbert, which has never voted Democratic since Franklin D. Roosevelt carried it in 1932, and Kit Carson County, which has also not voted Democratic since 1964. He was the first Democrat since Johnson to win a large block of counties in the western, central, and eastern portions of the state, including the typically Republican strongholds of Mesa, Delta, Montrose, Montezuma, Dolores, Archleuta, Jackson, Moffat, Mineral, and Rio Grande in Western Colorado; Park, Teller, Douglas, and El Paso in Central Colorado; and Baca, Lincoln, Cheyenne, Kiowa, Philips, Sedgwick, Morgan, Weld, Logan, Yuma, and Crowley in Eastern Colorado. He was also the first Democrat since Franklin D. Roosevelt in 1936 to win Washington and Hinsdale Counties, and the first since Bill Clinton in 1996 to carry Bent, Otero, and Chaffee Counties. Holland's best county was Costilla County, where he received more than ninety percent of the votes cast; Dickenson's best county was Rio Blanco County. Holland broke 60% in twenty Colorado counties, 70% in six counties; 80% in 1 county (Boulder County); and also received more than 90% in Denver County.
