There were a lot of first-time protesters at these protests. The material conditions are such that the number of "non-political" folk will be shrinking and they will be looking for something to do and get coopted by these events.

A lot of protests, riots, and strikes started organically in other revolutions (like the French or Russian one). The Bolsheviks were able to take advantage of the Russian ones even though they didn't organize them initially. I'm wondering if an organized left can eventually do something like that if these kinds of things continue to happen as US economic conditions break down.
