That's up to Bernie. He wants to maintain the rage etc, but what he says and more importantly, does will be key here.
I think at this point it's #NotAllBernieBros, and out of his hands, tbh.
Yeah, it's definitely not going to be Bernie people causing a ruckus. If anything, they'll be ones attacking the black block, if anarchists decide to show.
Yup, two weeks ago I was down in Westlake Square in Seattle to go to Nordstrom and there were a bunch of punk musicians playing and people walking around in black balaclavas and knife belts. Lots of Bernie signs as well as people asking for money for their own various causes where their begging signs also claimed they supported Bernie (for street cred I guess). I seriously thought it was a Sanders party.
Turns out it was an anarchist revolutionary event for May Day and got very violent shortly after I left.
If Sanders gives an open invitation to people to just show up in Philadelphia and cause trouble for the sake of causing trouble, rest assured he has a lot of supporters who will jump at the chance.
