Mainstream Democrats are finally jumping ship on Graham Platner’s now-defunct campaign for Senate in Maine. This isn’t a moral stand — it’s an electoral crisis.These Democrats were perfectly fine with Platner having a Nazi concentration camp tattoo, calling rural white Americans “stupid” and “racist,” mocking a wounded American soldier and saying he “didn’t deserve to live,” cheating on his wife, desiring to rape home intruders, blaming rape victims and saying they need to “take responsibility,” claiming black people don’t tip, telling a teenage girl who attempted suicide she wasn’t “trying hard enough,” having a profile on a site known for child predators, allegedly being abusive toward women, and being openly anti-police and pro-communist.It wasn’t until Platner’s polling numbers began to suffer, and a woman accused him of rape, that Democrats began to distance themselves from the oyster farmer and walking opposition ad campaign. Back in May, I said “principled Democrats” have gone extinct and that I would only change my mind if mainstream party members called on Platner to end his campaign. While some have turned on him, it was not out of principle, but out of opportunity and necessity.
