The thing is that the relentless trolling campaign against Oz was good (meaning effective) politics in Pennsylvania. It's a shame that it was used to elect a Zionist.
i think the charitable reading is that NJR doesn't think that fetterman's racist schlub routine is scalable and or motivating/leading a progressive movement, and he's certainly being proven right on that.
I definitely agree that his visual presentation would be a liability in most other states. But looking put together is not incompatible with the dirtbag shitposting strategy his campaign pulled off well.
It's also worth noting that Fetterman won against a quack TV doctor totally lacking in both charisma and signature policies. If we're thinking how reproducable his strategy is, the opponent matters.
