In the eleven Maine gubernatorial elections prior to 2016, only two candidates (incumbent governors
Joe Brennan in
1982 and
Angus King in
1998) won more than 50% of the vote. Typically gubernatorial elections have more than two significant candidates; the
2010 election had five candidates, with
Paul LePage emerging as the winner with 37.6% of the vote. Some public opinion felt that his victory was due to opponents of LePage dividing their votes between Democratic candidate
Libby Mitchell and independent candidate
Eliot Cutler. Proposals to enact ranked-choice voting have been introduced in the legislature as early as 2003, but were rejected. After a 2010 charter change, the city of
Portland began electing its mayor using ranked-choice voting in
2011. There were new legislative proposals in 2011, though they were rejected as well. In 2014, upon releasing his supporters to vote for someone else in the
2014 election, Eliot Cutler encouraged his supporters to support ranked-choice voting. Led by former independent
State Senator Richard G. Woodbury, Ranked Choice Voting collected more than the 61,123 valid signatures necessary to put a proposal to voters, collecting some 40,000 on Election Day 2014. The group collected 75,369 signatures and delivered them to
Maine Secretary of State Matthew Dunlap by October 19, 2015. Dunlap ultimately certified 64,687 signatures by November 18, 2015, which put the proposal on the November 2016 ballot. Per the Maine Constitution, the proposal went to the legislature in its 2016 session, but it did not act on the measure. On January 20, 2016, the
Maine House of Representatives voted to place the proposal on the ballot without holding a public hearing, over the objections of Republicans, led by Rep. Heather Sirocki, expressing concern about the constitutionality of the proposal.
Constitutionality Some, including a deputy secretary of state and a state legislator, expressed concern about the constitutionality of the proposal. Deputy Secretary of State Julie Flynn said that the Maine Constitution requires that the governor and state legislators be elected with a plurality of votes and that a system based on ranked-choice voting could be challenged in court. (The state constitution was amended in 1847, 1875, and 1880 to choose winners by
plurality for house, senate, and governor, respectively. Previously, an election with no
majority winner would be decided by multiple election rounds or by the state legislature.) Flynn also expressed concern that the proposal inserts the secretary of state into the process, while the Constitution states that votes shall be tabulated by municipal officials.
Maine Attorney General Janet Mills issued an opinion at the request of
Maine Senate President
Michael Thibodeau stating that while the referendum must appear on the ballot, it will likely require amending the Maine Constitution to implement it, in order to satisfy the concerns given by the Secretary of State's office. She added that the manner in which the proposal addresses how a tie in the voting should be addressed, drawing lots, directly conflicted with Article V of the Maine Constitution, which states that a tie in the vote for governor would be settled by the Maine Legislature meeting in joint session to choose a winner. The Committee for Ranked Choice Voting Maine dismissed such concerns, noting that a majority vote is always a plurality vote and that such a system has survived legal challenges in several other states. Its website statement also linked to statements by several Maine law professors supporting its arguments. After the question was approved by voters, the Maine Senate submitted questions to the Maine Supreme Judicial Court, which issued an advisory opinion on May 23, 2017. They unanimously ruled that ranked-choice voting was unconstitutional in state, but not federal, general elections. In response, the legislature passed a law on November 4, 2017, that amended the ranked-choice voting law to apply only to primary elections for Congress, governor, state senator, and state representative; and for general elections for Congress. The law survived a legal challenge in federal court by U.S. Representative
Bruce Poliquin, who lost reelection by ranked choice voting to
Jared Golden in
2018. ==Campaign==
