Maine Democrats meet to select Senate nominee to replace Graham Platner. Washington - Maine Democrats are gathering Saturday for the party's nominating convention to select a U.S. Senate nominee to replace Graham Platner on the ballot in November. Jackson effectively locked up the nomination, having informally secured a majority of the delegate slots. Jackson, 58 and a fifth-generation logger, was state Senate president from 2018 to 2024. He used to be a Republican and in his first state House race ran as a Republican. Jackson was first elected to the state House as an independent in 2002, but then became a Democrat.
