But the only way this is a “turn against him regardless of the other options” issue is if he’s a secret Nazi, so whether that theory is remotely plausible is the key question. Not “when did he know” or “did he really not see that one connect sketch that is, for most of us, the only time we’ve ever seen a tottenkopf”. And it’s just not plausible.

Anyone but secret Nazi is just a shade of “that was dumb/lazy/clueless of you”, which is not a reason to purge the progressive and just take whatever else we can.

I gather there is another progressive in the race that’s not taken off, so let them make their case and see if they can march his energy. If we have an option that’s drawing crowds and free from issues, cool, but if not, a guy with good intentions and some questionable decisions is easily better than an ancient neoliberal who’s going to die in office and play Susan Collins from the left until she does. Trying to push a nonsensical theory about a secret Nazi that even when they thought they were an anonymous shitposter on Reddit never acted like a Nazi is at this point indistinguishable from just trying to get Mills elected.
