Quick Answer
Graham Platner won the June 9 Democratic primary outright (72.1%) but withdrew on July 10 after a sexual assault allegation, which he denies. Maine Democrats held a replacement nominating convention in Bangor on July 25, where former state Senate President Troy Jackson defeated Saundra Pelletier 566–5 to become the Democratic nominee. Jackson did not appear on the June 9 primary ballot, so he has no primary vote share.
