The 2018 Maine House of Representatives elections took place as part of the biennial United States elections. Maine voters elected state representatives in all 151 of the state house's districts, as well as non-voting members from the Passamaquoddy Tribe and the Houlton Band of Maliseet Indians. State representatives serve two-year terms in the Maine State House.
A primary election on June 12, 2018, determined which candidates appear on the November 6 general election ballot. Primary election results can be obtained from the Maine Secretary of State's website.[1]
Following the 2016 state house elections, Democrats maintained effective control of the House with 77 members and 2 coalition Green representatives. Republicans held 72 seats following the 2016 elections. Following several vacancies and replacements between 2016 and 2018, on election day 2018, the Democrats had increased their majority to 74 Democrats, 1 Green, and 6 Independent representatives, while the Republicans had decreased from 72 to 70 seats.[2]
The Maine Secretary of State provides both a detailed description of each house seat as well as maps for each district, including this statewide House map showing all 151 House districts.[3]
The Democrats gained sixteen seats in the election, and the Republicans lost thirteen. The sole Green member — Ralph Chapman — was replaced by a Democrat, and the number of independents was reduced from six to five, with only two independent incumbents — Kent Ackley and Norman Higgins — being re-elected.
Italics denote an open seat held by the incumbent party, bold text denotes a gain for a party.
[4]21 incumbents (5 Democrats, 14 Republicans, one independent and one Green) were ineligible to run for a 5th consecutive term due to term limits.
