Maine State Auditor Matt Dunlap won the Democratic primary for the state's 2nd Congressional District through ranked-choice voting, overcoming the House Democrats' campaign committee's preferred candidate. Dunlap trailed state Sen. Joe Baldacci after initial ballots were counted, but advanced after lower-ranked votes were redistributed under Maine's voting system.
The result represents a setback for the Democratic Congressional Campaign Committee, which had endorsed Baldacci. The DCCC has faced repeated losses this cycle when backing specific candidates in primaries, signaling limited influence over grassroots Democratic voters.
Maine's 2nd District remains one of the nation's most competitive congressional seats. The district has shifted between parties in recent cycles, with Republican Bruce Poliquin holding the seat before Democrat Jared Golden won in 2018. Golden is not seeking reelection, opening the seat as a genuine battleground for 2024.
Dunlap, who has served as Maine State Auditor, brings executive experience to the general election race. His primary victory over a state senator suggests he mobilized support among progressive activists and Democratic base voters who rejected the establishment preference.
The use of ranked-choice voting proved decisive. Maine implemented this voting method statewide, allowing voters to rank candidates by preference. When no candidate achieves a majority on first-choice votes, the lowest-finishing candidate is eliminated and their votes redistributed based on voters' second choices. This process continues until someone reaches 50 percent.
The 2nd District general election will likely pit Dunlap against a Republican nominee. Both parties view the seat as winnable. Democrats need to defend or gain seats nationwide to maintain House control, making races like Maine's 2nd critical to the chamber's balance.
Dunlap's primary win demonstrates the DCCC's challenge in controlling Democratic races. The campaign arm faces
