The 2018 United States House of Representatives elections in Maine were held on November 6, 2018, to elect the two U.S. representatives from the state of Maine, one from each of the state's two congressional districts. The elections coincided with the elections of other offices, including a gubernatorial election, other elections to the House of Representatives, elections to the United States Senate, and various state and local elections.
These U.S. House elections were conducted with ranked-choice voting, as opposed to a simple plurality, after Maine voters passed a citizen referendum approving the change in 2016[1] and a June 2018 referendum sustaining the change.[2] Ranked-choice voting was used in the primary elections as well.[3]
While Rep. Chellie Pingree in District 1 was reelected with a majority, no candidate received a majority in District 2, which meant that the ranked-choice tabulation needed to occur. Rep. Bruce Poliquin, who received a plurality of first-round votes, filed a federal lawsuit to halt that tabulation, arguing that ranked-choice voting was unconstitutional. The court ruled against Poliquin in his request for a motion on November 15 and against the lawsuit itself on December 13. On November 15, Jared Golden was declared the winner after the ranked-choice redistribution, becoming the first member of Congress to be elected via ranked-choice voting.
