I guess I think those takes will probably be dumb, unless they're willing to look at the Democratic playing field systematically instead of cherry-picking just one or two races. Like, do you have a theory that explains both why Ocasio-Cortez won but also why establishment-ish Democrats did well in Colorado and why Cynthia Nixon doesn't seem to be going anywhere?
The other issue is that the tea party sometimes unseated incumbents -- or at least supposedly strong general election candidates in open-seat races -- in swing state and districts. New York 14 is extremely blue, by contrast, so there's no risk to Democrats in the general election.
