Personally not a fan of the DSA, and hate that a red rose twitter handle will be in Congress, BUT representation matters and for that reason, I think it's a good thing. I think many of the hot takes are blowing it out of proportion, however. Yes - progressives can win in places like *gasp* New York City. But the "DEMOCRATS NEED TO TAKE NOTE" thing is silly when OR, DSA, and other socialist style candidates have been crushed everywhere that isn't on a coast.
Like, being 3 or 4 out of dozens isn't a great record.
