I can't think of a greater price to pay actually. Losing donors and cash is (hopefully) a precursor to losing voters and mindshare. There's no better punishment than being utterly forgotten, relegated to the dustbin of history.
No, we cannot allow the current rise of fascism to be forgotten. We must be vigilant against it, always. Reminded that a slow burn of low-grade shit suddenly becomes a wildfire if you ignore it.
I just hope there is an opportunity to remember this as a near loss of democracy in this country, instead of a time we actually lost it.
