I don’t think it is because the GOP is incompetent. Cooley is a vastly more competent DA than the radical left Kamala Harris.
Whites now make up 41% of the population
Republicans make up 30% of the registered voters.
I think a lot of the answers lie in these numbers.
The white middle class has basically packed it bags and left the state, as Democrat supporting demographic groups have moved in. I live in LA. I know. All these mindless drones care about is having the “D” after your name inside the polling booth.
Harris is a hard leftist who will use the taxpayer's money to attack CA businesses with endless environmental suits. The violent criminals can breath a sigh of relief. She won't be pursuing them.
I’m always perplexed when someone attributes California election outcomes to demographic factors, particularly race.
Were it not for family members, who are either unable or unwilling to move, I too would leave the State that’s been my home all of my life! But, I’m in agreement with EricT, that “The Cal GOP is more like a country club for liberal old-money insiders. No conservatives need apply.” They did a piss-poor job of outreach, getting the “conservative” message out to the people. I suspect that they don’t know how to. But, not everyone in this state is an illegal alien or receiving government assistance!
