You be right. I spent a few decades watching my old county of residence (Ventura) turn from reliably conservative voting to liberal since I left 12 years ago.
Most is the massive influx of illegals, aided by those like we that left. Twenty years ago, there were areas you kept moving through Oxnard towards Channel Islands Harbor. Shudder to think what it is like now, especially as Calif prevents any personal means of protection.
Ventura/Oxnard used to be the place to be.
