Also certified, by write-in: Brent Andrews (Unaffiliated), Sigrid Ann Olson (Democrat), Gina Oswald (Independent), Joseph Steinberger (Faith in Humanity), Michael Turcotte (Un-enrolled) and Ashley J. Webb (Democrat).
Final candidate list: Maine Secretary of State. Faces and bars are the campaigns that hold the seat or have $25,000 raised or outside spending on file; being outside that group is a filing fact, not a mark. A candidate marked write-in is certified to run and their votes count; their name is not printed on the ballot. Not a prediction.
