2020 United States presidential election in Vermont

The 2020 United States presidential election in Vermont was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. Vermont voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. Vermont has three electoral votes in the Electoral College.

This is the first time Vermont was the strongest state for either party since 1956, when it was Republican Dwight D. Eisenhower's best state. Vermont also saw the largest increase in turnout from 2016, increasing 14.3%. Biden greatly improved on Hillary Clinton's 55.7% vote share and 25.9% margin from 2016, when third-party candidates received over 14% of the vote. Biden's performance was also the fourth-strongest Democratic performance in state history, as well as the third-largest Democratic margin of victory. Trump carried only one county, sparsely-populated Essex bordering New Hampshire, which had voted for the winner from 1980 to 2016. Consequently, Biden became the first president to win without the county since Jimmy Carter in 1976.

Another factor for Biden's improvement was strong support from Bernie Sanders, one of the state's U.S. Senators and a former candidate for the 2020 Democratic nomination who, despite endorsing Hillary Clinton, had received 5.7% of the vote in 2016 as a non-soliciting write-in candidate. Per exit polls by the Associated Press, Sanders maintained a 63% approval rating among his constituents, and his supporters broke 93% for Biden.
