2020 United States presidential election in Maine
The 2020 United States presidential election in Maine is scheduled to take place on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia will participate. Maine voters will choose electors to represent them in the Electoral College via a popular vote. The state of 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. In the 2016 election, Maine split its vote for the first time since 1828, awarding one electoral vote to Donald Trump as he got the most votes in Maine's 2nd congressional district.
Maine will be the first state ever to use ranked-choice voting for the presidential general election, with voters able to rank their preferred candidates on the ballot. Prior to 2019, no other American state thus far has used a voting system other than first-past-the-post or selection by the legislature to choose its presidential electors.

General election
Ballot access
Libertarian
The Libertarian Party was recognized by Maine as an official party in June 2016, but lost that status in December 2018. Consequently, Libertarian nominee Jo Jorgensen's only opportunity to appear on the ballot for the 2020 election is to appear as a nonpartisan candidate. To qualify for ballot access, Jorgensen must submit 4,000 petition signatures to the state by August 3. Jorgensen has sued the state for a reduction of the signature requirement, citing an increase in the difficulty of petitioning caused by the COVID-19 pandemic.Predictions
