California is the most populous for a reason.
Yes...there is a reason. It is run by anti-American assholes who have assisted 20 million illegal aliens of invading the United States by illegally offering “sanctuary” to them. Your elected officials are literally criminals who don’t uphold the law.
Oh, and there is also the whole promiscuity problem you have. You know, Hollywood, South Central Los Angeles, the porn industry, etc. all spreading herpes and having tons of babies out of wedlock.
So yeah, certainly no shortage of reasons. All of them also contribute to California being a third-world shit-hole that Americans are fleeing in record numbers.
