Maine law provides that all state and federal primary elections, and federal general elections, are conducted by ranked choice voting.
On November 8, 2016, Maine's Question 5, the Ranked Choice Voting Act, passed with 52% support, earning the second-greatest number of votes in the history of initiatives in Maine. The law stated that all primary and general elections for Maine's governor, state legislature, and federal congressional offices would be conducted by ranked choice voting.
Maine's first use of ranked choice voting under this law took place on June 12, 2018, when ranked choice voting was used in Maine's state and federal primary elections. At the same election, voters voted to continue using ranked choice voting for all future state and federal primary elections and for general elections for federal congressional offices (House and Senate). The first general elections conducted by ranked choice voting in Maine took place on November 6, 2018.
Following the success of Maine's 2018 ranked choice voting elections, legislation expanding the system to presidential primary and general elections passed August 30, 2019. However, opponents circulated a veto referendum petition, which will put the question of RCV for presidential primary and general elections on the 2020 ballot and suspend its implementation pending the outcome of that vote.
The Ranked Choice Voting Act has been subjected to various legislative and judicial actions. This page summarizes this history.
On October 19, 2015, Maine electoral reformers delivered over 70,000 signatures, mostly gathered by volunteers, to the Maine Secretary of State in Augusta. The Committee for Ranked Choice Voting, a grassroots group of Maine citizens, garnered broad support from across the political spectrum, all with a singular focus: uphold majority rule and give voters a stronger voice in elections. The signatures put the citizens initiative for ranked choice voting on the ballot for the November 2016 general election.
The initiative was certified as "Question 5" in June, 2016. The question was worded on the ballot as follows:
Do you want to allow voters to rank their choices of candidates in elections for U.S. Senate, Congress, Governor, State Senate, and State Representative, and to have ballots counted at the state level in multiple rounds in which last-place candidates are eliminated until a candidate wins by majority?
On Election Day, November 8, 2016, a majority of Maine voters voted yes on Question 5. It was codified into Maine election law.
After Question 5 passed, some, including the Maine Attorney General, expressed the opinion that parts of it could not be implemented because they contradicted parts of the Maine Constitution. This centered on archaic provisions of the Maine Constitution governing the election of its governor, as well as representatives to the state house and state senate stating that a candidate must be seated if they receive a "plurality" of votes. This concern stems from the colloquial use of "plurality" to mean "the most, but less than a majority" in the context of elections. Because a goal of ranked choice voting is to promote the election of candidates by a majority of votes rather than a mere plurality, some believed ranked choice voting violated these "plurality" provisions.
This concern had been raised during the campaign as well, but several high profile attorneys in Maine publicly stated that this language did not bar the use of ranked choice voting. Rather, "plurality" in the Maine Constitution meant that the candidate must be seated if they win the most votes at the end of the election, without dictating how the votes were to be counted. They pointed out that these provisions had been put in place to replace the old system by which an election simply failed if no candidate received a majority. When an election failed, offices like the governor could be appointed by the state legislature. Similar provisions exist in many state constitutions, generally to replace provisions that allowed for appointment or repeated elections in cases where no candidate receives a majority of votes.
The Maine Constitution has another unusual provision that allows the governor or a branch of the state legislature to essentially ask the Justices of the State Supreme Court for their non-binding opinion on an important matter. The Maine State Constitution says that the Justices should do so "upon solemn occasions," and so the procedure is called a "solemn occasion." On February 2, 2017, the Maine State Senate voted 24-10 to ask the Justices for their opinion on whether the Ranked Choice Voting Act contradicted the "plurality" provisions in the Maine Constitution.
The Maine Supreme Judicial Court accepted briefing and heard oral argument on the question. FairVote was among those who submitted a brief arguing that there was no conflict. Others included the Committee for Ranked Choice Voting, the Maine League of Women Voters, national scholar Larry Diamond, and the preeminent scholar on the Maine Constitution, Marshall Tinkle. Nonetheless, on March 23, 2017, the Justices issued their advisory opinion concluding that general elections for governor and state legislature could not be conducted by ranked choice voting due to the plurality provisions.
The opinion was purely advisory, leaving the law in place. Also, because no such plurality provisions exist for either primary elections or for the election of federal congressional offices, the Justices did not find any issue with applying ranked choice voting to those elections.
Because the "solemn occasion" had no direct legal effect, the Maine legislature had the responsibility to either amend the Maine Constitution or to amend the Ranked Choice Voting Act. If they failed to do either, then the state would be obligated to conduct all state elections by ranked choice voting, which would inevitably result in a lawsuit.
However, the state legislature could not agree on the correct path forward. Bills were introduced in June 2017 that took various approaches, but all of them failed. After the legislative session ended, the Maine legislature called a special session in October, and hastily passed "An Act to Implement Ranked-choice Voting in 2021." That bill stated that ranked choice voting would not be implemented in 2018 or in 2020, and then the entirety of the Ranked Choice Voting Act would be automatically repealed unless the Maine Constitution were amended prior to December 1, 2021.
Effectively, this bill was a repeal of the Ranked Choice Voting Act that the people had passed directly less than a year prior, because Maine has a particularly difficult process for amending its state Constitution, requiring supermajority votes in the state legislature.
Immediately after the delay-and-repeal bill passed, the Committee for Ranked Choice Voting began a campaign to save ranked choice voting in Maine. In Maine any law passed by the state legislature can be blocked by a "people's veto." The people must petition to stop the law. If they gather enough signatures in time, the law is suspended and at the next election voters decide whether to block the law permanently.
Mainers successfully gathered more than 80,000 signatures in 88 days, suspending the law. As a result, the 2018 primary elections were conducted by ranked choice voting, and at the same election, Maine voters voted on whether to block the law permanently. Importantly, the people's veto excludes the portions of the delay-and-repeal law regarding general elections for governor and state legislature, meaning that ranked choice voting will not apply to them. Therefore, the people's veto both protected ranked choice voting and avoided all legal issues resulting from the solemn occasion.
On March 29, Maine Secretary of State Matt Dunlap raised a legal question regarding whether the people's veto really did require the June primaries to be conducted by ranked choice voting. On April 3, the Maine Superior Court held that it did. The Maine Senate quickly voted, along party lines, to enter the litigation and argue, based on a variety of theories, that Maine should not implement ranked choice voting. This quickly led to the Maine Supreme Court unanimously rejecting those claims and unambiguously concluding that "ranked choice voting is the law of Maine with regard to the primary elections on June 12, 2018."
In early May, yet another legal challenge was levied, this time by the Maine Republican Party. It adopted a rule declaring that its party nominations are decided by plurality at its state convention on May 4th, and the very same day filed a lawsuit in federal court arguing that the First Amendment to the United States Constitution requires that Maine respect its new party rule and not apply ranked choice voting to its primaries. On May 29, federal district court Judge Jon Levy, himself a former Justice of the Maine Supreme Judicial Court, rejected that claim, holding that Maine has a legitimate interest in applying ranked choice voting to primary elections.
Maine's first use of ranked choice voting therefore took place in its primary elections on June 12, 2018. At the same election, Mainers voted on Measure 1, which decided whether to retain ranked choice voting going forward for all future primary elections as well as general elections for federal congressional offices. Measure 1 passed with more than 54 percent in favor. Consequently, ranked choice voting was used to elect federal congressional offices on November 6, 2018 and will continue to be used in Maine's state and federal primary elections and in its federal general elections going forward.
After Election Day, November 6, 2018, it became clear that Maine's Senate race as well as its 1st Congressional District would be decided in the first round, while its 2nd Congressional District would go to multiple rounds. After Election Day, but before the Maine Secretary of State had conducted the round-by-round count for the 2nd Congressional District, the Bangor Daily News released analysis of exit polling that suggested that incumbent Republican Bruce Poliquin, who led in first choices, would likely lose to Democratic challenger Jared Golden in the ranked choice voting count. Four days later, Poliquin filed a federal lawsuit arguing that ranked choice voting was unconstitutional and asking the court to stop the Secretary of State from releasing any ranked choice voting count.
On November 15, Federal District Court Judge Lance Walker released his opinion, denying Poliquin's request to stop the vote count from proceeding. The opinion noted that "no constitutional infirmity appears likely," and said he was "not persuaded that the United States Constitution compels this Court to interfere with this most sacred expression of democratic will by enjoining the ballot-counting process and declaring Representative Poliquin the victor."
Later that day, the Secretary of State released the round-by-round count, which confirmed that Bruce Poliquin had lost his seat, with a narrow majority preferring Jared Golden after the elimination of the two independent candidates. Poliquin requested a recount, which began on December 6 and proceeded quickly and smoothly, with no notable change in the result. He abandoned the recount on December 14, before it was completed.
The earlier judicial opinion only involved the threshold question of whether to stop the count. Poliquin maintained the lawsuit, which drew additional briefing from Jared Golden, from independent candidate Tiffany Bond, and from the Campaign Legal Center as amicus curiae. On December 13, Judge Walker announced his final judgment in the case, rejecting each of the legal arguments brought by Poliquin and the other plaintiffs.
On December 18, 2018, Poliquin and the other plaintiffs appealed the order to the First Circuit Court of Appeals, requesting an emergency injunction to stop Golden from being seated. After briefing from all parties, the First Circuit denied the request on December 21, with a brief per curium statement: "Plaintiffs-Appellants' Emergency Motion for Injunction Pending Appeal does not show movant to have a strong likelihood of success on the merits and is denied. So ordered."
On Christmas Eve, Bruce Poliquin announced that he was conceding the election and wished Jared Golden the best. On December 28, Governor Paul LePage signed the certificate of election stating that Jared Golden had won election to Congress in CD-2.
Following the success of Maine's 2018 ranked choice voting elections, legislation expanding the system to presidential primary and general elections passed August 30, 2019, and on September 6, 2019, Governor Janet Mills (who had been nominated in Maine's first ranked choice voting gubernatorial primary) said that she would delay action on the bill, so that it would go into effect for Maine's 2020 presidential general elections, and then be used for presidential primaries beginning in 2024. Maine therefore began preparing to run the first ranked choice voting general election for President.
In an effort to prevent the expansion to the presidential election, the Maine Republican Party began gathering signatures for a veto referendum. If successful, such a referendum would suspend the law, meaning that the presidential election would be conducted by single-choice plurality and not ranked choice voting. It would also ask Maine voters to vote on whether to veto the expansion entirely on November 3. On June 15, the Maine Republican Party turned in approximately 68,000 signatures for the veto referendum. On July 15, the Maine Secretary of State reported that only 61,334 signatures were valid, short of the required 63,037 signatures, but on August 24, 2020 a Maine Superior Court Judge ruled that some of those signatures were improperly invalidated, resulting in the veto referendum having just enough signatures to appear on the 2020 ballot. However, on September 8, the Maine Supreme Judicial Court stayed the lower court decision, effectively moving forward with RCV for president. On that date, Maine Secretary of State Matt Dunlap announced that ballots would be printed with RCV for president and that the veto referendum would not appear on the ballot.
Additionally, opponents filed another lawsuit in federal district court arguing that ranked choice voting was unconstitutional on grounds similar to those brought in Baber v. Dunlap. The case was assigned to Judge Walker, the same judge who heard Baber. Following an expedited briefing, including an amicus curiae brief from the Princeton Electoral Innovation Lab, Judge Walker released his order rejecting the challenge, and reiterating the legality of ranked choice voting in Maine. Consequently, although Maine's use of ranked choice voting in presidential elections remains in question, the system's future in state primary elections and congressional general elections remains secure.
Maine voters successfully voted with ranked choice voting for president in November 2020. Maine allocated its four electoral votes by congressional district, each of which was determined using RCV. One electoral vote went to Joe Biden for winning the RCV race in the first congressional district, one vote to Donald Trump for winning the RCV race in the second congressional district, and two additional votes to Biden for winning the statewide RCV tabulation.
With no pending legal challenges after the 2020 general election, Maine is expected to use RCV for presidential primary and general elections, as well as other eligible federal and state elections.
