The 2024 United States presidential election in Colorado took place on Tuesday, November 5, 2024, as part of the 2024 United States presidential election in which all 50 states plus the District of Columbia will participate. Colorado voters will choose electors to represent them in the Electoral College via a popular vote. The state of Colorado has 10 electoral votes in the Electoral College, following reapportionment due to the 2020 United States census in which the state gained a seat.
A fast-growing Mountain West state that was formerly Republican leaning, no Republican has won Colorado by double digits at the presidential level since Ronald Reagan in his 1984 landslide re-election victory. Colorado was consistently competitive at the presidential level from the late 1980s going through the 2010s, including Hillary Clinton narrowly winning the state by 4.9% in 2016. In 2020, Democrat Joe Biden carried the state by 13.5%, becoming the first presidential candidate to win Colorado by a double-digit margin since Reagan. The last Republican to win the Centennial State's electoral votes was George W. Bush in his 2004 re-election victory, which he won by a margin of 4.7%. Since then, the state has shifted to the left and broke substantially for Joe Biden in 2020. Today, Colorado is a blue state, with Democrats winning the state in every presidential election starting in 2008, occupying every statewide office since 2023, and holding comfortable majorities in its state legislature.
Notably, Colorado did not see a significant shift rightward compared to other blue states[1] (though Republicans did gain one seat in Colorado's congressional delegation, CO-08 in the North Metro). Harris won by 11%, only 2.5% down from Biden in 2020, significantly better than Hillary Clinton's margin of 4.9% in 2016, and exceeding Barack Obama's margins in both 2008 and 2012. Trump flipped Pueblo County, which he had won in 2016 but lost in 2020. Nonetheless, he became the first Republican to win the White House without carrying Chaffee or Garfield Counties since William Howard Taft in 1908. This is the first time since 2000 that Colorado voted for the popular vote loser, and the first time since 1908 that it voted for a Democrat that lost the popular vote.
Indicative of its trend to the left, Colorado has voted further left in this election than states like New Jersey and Illinois that were previously considered much more blue than Colorado, and only 0.4% to the right of New York state. This is the first time since 1964 that Colorado voted to the left of Illinois.

The Citizens for Responsibility and Ethics in Washington, a left-leaning non-profit, filed a lawsuit on behalf of four Republicans and independent voters, saying that Donald Trump is ineligible to run for president because of a section in the 14th Amendment that states "no person shall ... hold any office, civil or military, under the United States ... who, having previously taken an oath .... as an officer of the United States ... shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof". A trial on this case took place during October and November 2023.[2] The judge found that Trump engaged in insurrection but declined to remove Trump from the primary ballot, saying there is "scant direct evidence regarding whether the Presidency is one of the positions subject to disqualification". On December 19, 2023, the Colorado Supreme Court ruled that Trump is disqualified from the Presidency under Section 3 of the 14th Amendment and ordered that Trump be removed from the 2024 Colorado Republican presidential primary ballot.
Trump appealed this ruling to the Supreme Court of the United States, and arguments were heard in February. The Colorado decision was stayed pending appeal, and Trump was included on the certified ballot, which began to be mailed to overseas voters on January 20. On March 4, 2024, the Supreme Court issued a ruling unanimously reversing the Colorado Supreme Court decision, ruling that states had no authority to remove Trump from their ballots, and this was instead a power held by Congress.
The deadline for minor party candidates to qualify for the ballot was July 1, 2024, while independents could petition for ballot access until July 11. In September, Colorado secretary of state Jena Griswold published the following candidates as certified to appear on the general election ballot:
Additionally, the state published a list of certified write-in candidates, the deadline for which was on July 18:
