What are the odds that these people are 95% Democrats and 5% socialists or anarchists, and that none are Republicans?
I wouldn’t take those odds, there would be lots of democrats, about zero conservatives, lots of libertarians, probably a small but more than we think number of moderate/log cabin republicans, and a few from the greens and such.
This is a fetish/performance art/sexual fetish/weird party thing, that probably attracts people who aren’t 100% in sync in their politics and normal lives and probably gets participants who get involved for a period and drift away.
