LEWISTON — Samuel Chamberlain will face Republican Ronald Chicoine in November for Androscoggin County’s 2nd District seat on the expanding County Commission.

Vote results Tuesday night were Chamberlain, 333; Walter Hill, 196.

Hill, 45, has served on a variety of local boards, including the Planning Board and the school board. Chamberlain, 20, works at the Maine People’s Alliance and serves as an AmeriCorps volunteer.
