Democrat Jared Golden has defeated incumbent Republican Bruce Poliquin in the closely-contested race for Maine's 2nd congressional district. Golden prevailed via the state's ranked-choice voting process, which kicked in when none of the candidates received a majority of the initial vote in this four-person race.
Maine's largely rural 2nd district - the largest by area in the Eastern Time Zone - went for Donald Trump by 10 points in 2016. This earned the president an electoral vote in the state, which is one of only two that uses an allocation method other than winner take all.
Democrats now have 231 seats, Republicans 199, with five contests remaining undecided.

Biden is likely to prevail here, but a competitive electoral vote available in the state's 2nd congressional district - won by Trump in 2016 - will draw considerable attention.
See how often a state votes with the election winner and also which states most frequently put the winner across the 270 electoral vote threshold.
Reliably Republican at the presidential level through most of the 20th century, it has voted Democratic since 2008 and looks fairly safe for Joe Biden in 2020
