We left SoCal in 2010. Emergency rooms were over-run with illegals (and they were “served” before all others), crap uninsured vehicles with Mexican logos were all over the highways, and there were times that during a trip to the grocery store no English was spoken. Human Resources offices coddled minorities; normal Americans were brow-beaten into “accepting” the invasion and we had to live our lives in STFU mode.
I think Californians are receptive to Trump, his wall, and common-sense approach to trying to make American great again.
I try to tell everyone I can how ugly an invaded state can be. And to not let it happen here! I consider it my duty, after escaping Mexifornia for all the reasons you said. I wish I had taken videos of an average trip to walmart or a restaurant - nobody here in the US would believe how bad it is.
