In my area the movement is growing. Its also a solid coalition of many diverse orgs, think PSL, PYM, and other decent M-L orgs. The number of volunteers is growing. I saw on PSL Los Angeles (not where I live but I follow their instagram for interest) that there was a line around their block for the organizing meeting, just hours after the march.

People are hungry for getting organized, people are inspired by MN, and in places with strong coalitions involving M-L orgs, I think the movement still has potential to grow at a rapid pace. I don't know when we will get to a true "nationwide general strike" territory, but I am feeling the optimism from being out there today.
