For example, https://www.cagrocers.com/california-repeats-worst-run-state...
It has a broad reputation for dysfunction in basically every area. Energy -- it imports 20% of its electricity from the rest of the nation's grid to get around wacky anti-carbon rules for domestically produced energy, and as a result has the highest energy costs in the nation as well as suffering from rolling blackouts. It is the state of constant fires because of forest mismanagement due to a politically influential "don't chop down our precious trees" faction. (California's chronic fires are also blamed on global warming). It has one of the worst education systems and a truly insane educational policy ("we will create 5 million Galois' by eliminating math classes!"). Terrible homeless problem. Terrible crime problem. A shrinking population. Massively dysfunctional housing market. And one of the highest tax burdens. Massive infrastructure problems.
Etc.
It's really hard to think of any area of public policy - from tax policy to education to energy or crime -- and say "Hey, what California is doing is working really well, we should emulate that". Just compare how California stood in areas like test scores, crime, housing affordability, energy prices in 1970 versus 1990 versus today. You see a peak and then a decline followed by collapse.
