I agree; apparently some tech zillionaire poured one million dollars of his money from California into the HOD races; I really wonder if the Reps were caught flatfooted by it. While this is a wipeout (especially for HOD), I expect the Dems to overreact nationally (they always do) and they will do something stupid in response; they will be very cocky and cockiness always leads to disaster.
The Trump Justice Dept will keep them from gerrymandering away more than three House Republicans... but that’s bad enough.
