Technically this was because NYC-DSA requested to withdraw their nomination (which had already been approved) so as not to have a public rift and not because of her atrocious politics. Ultimately probably good for the org to cut ties before she votes for a bill saying Palestinians are subhuman but it's still kinda pathetic.
Oh it's absolutely pathetic. They should have cut ties with her when she backpedaled her first marginally pro-palestine interview shortly after she got elected (if I'm remembering correctly, could've been before). But the DSA isn't a serious organization so we get this too little too late severing.
