The Southland is a desert and it was poor planning to have such a huge population there to begin with. He is willing to devastate NorCal and farmland to send water to the rich Hollywood types and all the illegals.(full disclosure, I’m from NorCal).
I remember when California was attempting to get water from the Columbia River pumped to them back in the 60’s and 70’s.
I'd rather tear up and pave a desert than the prime farmland that was the Los Angeles basin and San Gabriel Valley.
