Maine's Ranked Choice Voting: How It Works in 2026 Federal Races
Maine is the only state using RCV in federal elections. The 2018 ME-2 race was the first federal election ever decided by RCV. In 2026, RCV applies to Collins' Senate majority math, Golden's ME-2 defense, and ME-1. Who benefits from spoiler candidates?
Maine RCV: Key Facts and 2026 Race Applications
| Feature / Race | Detail | Applies? | Who Benefits |
|---|---|---|---|
| RCV adopted by voter referendum | 2016 (56% Yes) | Upheld after legal challenges | Voters chose it |
| Federal races covered | US Senate + US House (primary + general) | Yes, all federal | Field-dependent |
| State races covered | NO — state uses plurality | Governor, state leg = no RCV | Plurality winner |
| Presidential Electoral Vote (ME-2) | Plurality — no RCV | ME-2 EV can split from ME | Trump won 2024 |
| Senate race (Collins 2026) | RCV applies | Multi-candidate field possible | Unclear |
| ME-2 (Golden defense) | RCV applies | 2018 historic precedent | Golden benefited before |
| ME-1 (Pingree) | RCV applies but Safe D | Rarely goes to RCV rounds | Academic |
| 2018 ME-2 outcome change | Golden won via RCV rounds | Poliquin led after round 1 | Changed winner |

Three Dimensions of RCV in Maine 2026
The Golden-Poliquin Race: First Federal RCV Finish in History
In November 2018, Republican incumbent Bruce Poliquin led Democrat Jared Golden by approximately 2,600 first-choice votes after election night, with two minor candidates (independent Tiffany Bond and Green Party candidate Will Hoar) together receiving nearly 8% of the vote. Because no candidate had more than 50%, Maine's RCV process was triggered for the first time in a federal race.
After both minor candidates were eliminated and their votes redistributed according to second choices, Golden received enough second-choice transfers (primarily from Bond and Hoar voters who preferred the Democrat as their second choice) to surpass Poliquin and win by approximately 3,500 votes.
Poliquin sued, arguing RCV was unconstitutional, but federal courts rejected his challenge. The case established that RCV is constitutionally permissible in federal elections under Maine's state authority to regulate federal elections within its borders. The 2018 result became the national reference point for understanding RCV's electoral consequences in competitive three-way races.
Who Benefits from Spoiler Candidates Under RCV?
RCV eliminates the traditional spoiler problem: under plurality voting, a third-party candidate who draws votes disproportionately from one major-party candidate can hand victory to the other. Under RCV, voters can rank a third-party candidate first without "wasting" their vote, because if the third-party candidate is eliminated, their vote transfers to their next ranked choice.
In Maine's 2026 races, this matters most for Golden's ME-2 defense. If a libertarian-leaning independent enters the race and draws first-choice votes from moderate Republicans who dislike both the major-party candidates, those votes could transfer to Golden in an RCV round if the independent is eliminated. This is essentially what happened in 2018.
For Collins' Senate race, RCV's impact depends on field composition. A progressive third-party challenger drawing Democratic votes would, in RCV, likely transfer those votes to the main Democratic challenger anyway — meaning RCV wouldn't help Collins unless moderate Democrats could be persuaded to rank her second, which is unlikely given the 2026 environment.
How RCV Changes Campaign Strategy in Maine Races
RCV fundamentally changes campaign strategy by incentivizing candidates to appeal beyond their base. Under plurality voting, candidates can win with 35-40% of the vote in a crowded field by energizing their core supporters. Under RCV, candidates who are everyone's second-worst choice — but no one's first — can lose even with significant support. Candidates who build broad coalitions and avoid alienating opponents' supporters can win RCV rounds.
This dynamic rewards Golden's brand in ME-2: his willingness to break with his party and appeal to moderate Republicans makes him the second-choice candidate for many voters who prefer a Republican first but would rather have Golden than a more liberal Democrat. In an RCV system, those second-choice preferences are electoral gold.
Collins' brand similarly depends on being acceptable (if not preferred) to many Democratic and independent voters. In a two-way race, RCV doesn't change anything. But if a strong independent enters her 2026 elections and draws votes from both sides, Collins' ability to attract second-choice votes from independence-valuing moderates could be decisive in the RCV rounds.
