Personally i have heard the critiques of Zohran's campaign, most of which i agree with (personally unless this leads to a 100k more new members, i am still not sold on endorsing executives considering the complicity running police departments brings), it is harder to argue DSA isn't trying to take advantage of the publicity.
DSA national recently announced it's membership drive, specifically because huge wins like this have lead to huge influxes of new membership. So now rank and file members are primed to start reaching out to people who are celebrating this win
I know much of this lot is more psl or anarchist aligned, but if you are considering DSA now would definitely be the time!
