I get the idea of flatten the curve but states that already got hit hard don't really have any reason to impose additional restrictions they wouldn't do anything.
It's pretty obvious to people watching that the impression was created by liberal media that just wants to bash conservatives.
A cursory check of the numbers shows that it has no basis in reality.
Top 5 states:
Louisiana, Mississippi, Florida, North Dakota, Alabama

In any event TX, NJ, and FL all have similar reported COVID deaths, but CA has fewer excess deaths than TX or NJ. Some of that is probably due to e.g. reduced automotive mortalities under more stringent lockdown, but I don't think the data you posted indicats that CA is e.g. worse than the other 3 states at reporting COVID deaths (otherwise we would see a much higher excess death count in CA compared to those 3 states).
