This means he can be replaced with another Democrat
Graham Platner can be replaced as the Democratic nominee for Senate in Maine if he withdraws from the race by next Monday, and state law would then give the state Democratic Party until July 27 to name a replacement.
They need to listen to Pelosi from 2024. Hold a primary. A rapid primary, but a primary regardless.
The RCV aspect of their primary would also be very valuable, since it sounds like there will be a lot of options and little time to coalesce.
