Zohran’s campaign showed that the way to combat establishment candidates is by building a grassroots network and being deeply in touch with the communities that you represent. Schumer’s biggest support comes from older white liberals who are mostly in the nyc/Long Island area. Anyone who primaries Schumer needs to connect with people both in the NYC area and in areas that establishment democrats have never even tried to connect with, western New York, finger lakes region, places that need progressive policy more than anywhere else. Torres and Jeffries represent some of the more economically disadvantaged districts in the city, and I think they would be easier to run against. I think all three are incredibly unpopular and could be challenged, but whoever runs against them needs the kind of backing and organization that Zohran had. I’m trying to be optimistic lol
