A candidate will participate in the 2026 Maine Democratic Senate primary election, with the final certified vote share determining the outcome across multiple possible ranges.
Janet Mills' vote percentage in the 2026 Maine Democratic Senate primary is calculated as total votes received divided by total valid votes cast, multiplied by 100 and rounded to specified decimal places. Resolution uses certified official results only, including write-in votes if they appear in certified results while excluding invalid or spoiled ballots.
