Troy Jackson is all but certain to replace Graham Platner as the Democratic nominee after rival candidates dropped out and his supporters swept delegate elections, effectively turning the party’s open nominating process for Maine Senate into a near-coronation. 

Jackson has secured the support of a majority of the state party delegates who will choose Platner’s replacement on July 25, effectively locking up the nomination before the convention convenes and clearing a path to face Sen. Susan Collins (R-ME) in November.
