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.
So you have no defense for trying to push “he has changed so much” as an excuse other than tone policing, ad hominem, and continuing to link to a blog post that I am increasingly certain you haven’t actually read.
Oh reddit.
