Sorry, TX and FL are a couple decades behind California but on exactly the same demographic trend. This won’t end well for the Republic, unfortunately.
Without California Texas and Florida could control the illegal immigration problem.
Demographics are not destiny if you do something about it
But Texas and Florida don’t have Hollywood and all the coastal progressives. And, the majority of counties in both states have voted Republican in presidential elections, whereas in CA it’s been 50/50.
Texas and a few other states have their own secessionist movements and idiots but it’s more fun to rag on California. Actually they all should be cheering on Texas too, that way between California and Texas they will have eliminated the majority of illegals.
Long before that there will be something like SMOD (sweet meteor of death), cleansing solar EMP (or man made), financial collapse or plague and the social parasites will be drastically reduced. We just need to make sure in the Republics rejuvenation that politicians are never allowed to dispense largess again, like the penalty for a politician proposing such a thing would be being dissolved in acid or something equally horrible...
If CA were to leave, illegals in their land would instantly become citizens of the new nation by proclamation of the new government. It would have to be absolutely clear that CA could never return, given that government’s policy of open borders.
