Democrat incumbent Evalyn Merrick apparently lost her seat for Coos District 7 by 12 votes, according to an unofficial tally compiled by the Associated Press.
Merrick had 3,253 votes compared to Republican Leon Rideout who had 3,265.
The official tally by the New Hampshire Secretary of State is not yet available.
Earlier in the evening, when only five of the 10 precincts were counted, Merrick had a lead of just over 100 votes.
