Rep. Chellie Pingree, a Democrat, has won another term representing Maine's 1st Congressional District, beating Mark Holbrook, a Republican.
With all precincts reporting, Pingree has 58.8 percent of the vote, followed by Holbrook with 32.5 percent.
Pingree has represented the district in the House since 2009.
Maine is using ranked-choice voting this year, in which voters number their choices from first to last. In this system, if one candidate doesn't have more than 50 percent of the votes, the candidate with the fewest No.1-ranked votes gets eliminated, and those ballots are credited to the candidates each voter listed as their second choice. The process is repeated until one candidate has a majority.
Democrats have gained a majority in the House, with 235 seats in the next Congress. Both of Maine's House seats have been decided; one switched hands, going to Democrats.
The number of votes cast for Democrats in House races has increased 55.0 percent from the 2014 midterms, compared with an increase of 25.6 percent for Republicans.
The district went for Democrat Hillary Clinton in 2016 by a margin of 14.8 points. Clinton won Maine by three points.
