When Graham Platner first appeared on the scene, I got it. I got the vibe. He had the sort of rough charisma that seemed like it would appeal to Mainiacs.
The sheer number of red flags that have popped up has obviously given a lot of people real qualms about this guy. It is very difficult to support a guy who casually carried a Nazi tattoo for years or said some of the dumbassed things he's said.
However...
Defeating Susan Collins is an imperative. Platner is leading in the polls, but previous challengers to Collins have been leading at this point.
What worries me is that there are a LOT of people online who are furious at Platner and his accumulated misdeeds. Many are rightfully worried about a repeat of John Fetterman, a guy who got into office based on vibes.
Still, it pains me to see good people taking sides on this. As soon as you take a firm side, you cannot move off it easily. This is true of MAGA and the Bernie Bros. You dig in; you refuse to compromise; you approach this as a zero sum endeavor.
You absolutely do not have to support him. If you want to defeat Collins, just ignore him (unless you live in Maine). Stop creating an identity around intramural conflict, because you're going to have to move on at some point.
