The percentage may be “high”, but many of the counties reflected in the map are red counties...meaning a good portion of that 23% are conservatives or at a minimum, republicans.
We’re not all liberals out here...and about the only thing that prevents me from moving to TX is the “welcome” I expect because of the CA tags on our vehicles...all the “stay home parasites” type Texans can keep it for all I care...their crap must smell like roses or something.
Look at the counties in the states with outflow and go from there...that will give you a better image of what is more likely happening. The NE, Miami-Dade, NW, etc. are well-known liberal enclaves...even Clark County NV is shown.
What CA has suffered from the other 49 states in the Union is bound to happen to others...CA is the “benefactor” of having a vibrant economy and prospects some 40 years ago...liberalism bled it dry.
Texas’ own success may well precede its doom...
I get what you are saying. Makes sense. My cousin is leaving CA after 30 years this October. Taking his family & 30 jobs with him.
