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’re not allowing this one to slip by: they really want the seat. But what they are doing is what the GOP never does, and that is hold their own people accountable for being criminals, even if it means losing political power. Platner, Menendez, Swalwell, (I could go on) Dems will hold even powerful members accountable for this stuff (ever since Clinton; there was a real soul searching within the party about him).
They’re going to fight hard for this seat. They just not going to do it with Platner.
