2016 United States presidential election in Maine

The 2016 United States presidential election in Maine was held on Tuesday, November 8, 2016, as part of the 2016 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, businessman, reality television host of The Apprentice, media personality and real estate mogul Donald Trump, and running mate Indiana Governor Mike Pence against Democratic Party nominee, former Secretary of State Hillary Clinton, and her running mate Virginia Senator Tim Kaine. 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. The last time it did so was in 1828. Maine was once one of the most Republican states in the nation. It voted for the Democratic ticket only three times (1912, 1964, and 1968) from 1856 to 1988, but a Democrat has won the state's popular vote in every election since then. Although regarded as a safe blue state prior to the election, Maine shifted dramatically and unexpectedly towards the Republicans, with Clinton's 2 % margin of victory the narrowest for a Democrat since 1988, when Republicans last won the state, and well down on Obama's 15 % margin in 2012. As a measure of how Republican Maine once was at the presidential level, Trump is only the third Republican to win the White House without winning the popular vote in Maine after Richard Nixon in 1968 and George W. Bush in both his 2000 and 2004 campaigns. Maine's significant Republican shift was largely attributed to Trump's stronger than expected support from the state's rural white working class voters, a demographic that overwhelmingly supported Obama in the previous two elections. On election day, Clinton carried Maine's two at-large electoral votes with a plurality and won Maine's 1st congressional district, while Trump won Maine's 2nd congressional district, making him the first Republican to do so since George H. W. Bush in 1988 and also making him the first Republican to win an electoral vote from a New England state since George W. Bush won New Hampshire in 2000. In addition to the historic electoral vote split in Maine, this marked the first time that such a split occurred after Maine began awarding electoral votes based on congressional districts in 1972. This was also the second time that a state split its Electoral College vote by congressional district since Nebraska in 2008.
