2020 United States presidential election in Maine

The 2020 United States presidential election in Maine 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. Maine 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. Maine has four electoral votes in the Electoral College. Unlike all other states except Nebraska, Maine awards two electoral votes based on the statewide vote, and one vote for each congressional district.

On election day, Biden carried Maine at-large by nine percentage points and the 1st congressional district by 23 percentage points, garnering three electoral votes. However, the rural 2nd district backed Trump by more than seven percentage points, giving him one electoral vote. This was the same result as 2016, and as such marked only the second time since 1828 that Maine split its electoral votes, as well as the first time since 1828 where the winner of both the election and the national popular vote did not receive all of Maine's electoral votes. Finally, it's also the first election where ME-2 didn't vote for the winner of election and the winner of the national popular at the same time while ME-1 and Maine at large did the opposite.

Maine became the first state to use ranked-choice voting for a presidential general election, with voters able to rank their preferred candidates on the ballot. Majorities were reached in the first round of voting statewide and in each congressional district, so ranked-choice voting's vote transfers and special tabulation were not required.

Biden performed strongly with college-educated voters to win Maine. Maine weighed in for this election as 5% more Democratic than the national average. This is the only state that his running mate Kamala Harris won in 2024 where she received a larger vote total than Biden in 2020.

Primary elections The primary elections were held on Super Tuesday, March 3, 2020.

General election Ballot access The Libertarian Party was recognized by Maine as an official party in June 2016 but lost that status in December 2018. To qualify for ballot access, Jorgensen was required to submit 4,000 petition signatures to the state by August 3. Jorgensen sued the state for a reduction of the signature requirement, citing an increase in the difficulty of petitioning caused by the COVID-19 pandemic. Jorgensen was successful in appearing on the ballot.
