California was the first state to issue a stay at home order, has mandated masks for months, and has been one of the 10 most restrictive states over the past three months; Florida has no state mask mandate, no lockdown and is one of the least restrictive states in the country.
Florida and California are two of the three largest states by population and both have sunny, warm weather and reside on a similar latitude. One has had open theme parks for months; the other has never allowed Disney to open. Let's compare how they are doing...
Cases in California are now 4X higher than in Florida. Both saw a spike in the Summer, but California's late Fall growth in cases is dramatically worse than Florida's:
There are also more than 3X as many people hospitalized with Covid in CA compared to Florida:
In FL, the Fall wave of cases has only driven a moderate growth in fatalities, which appears to have already peaked. Meanwhile, deaths in CA continue to grow rapidly and are currently 2.5X higher than that seen in FL:
The same story holds for cumulative excess mortality this year, with CA doing worse than FL - and the gap is growing - despite Florida having a significantly older population:
So, even accounting for California's larger population, Florida has dramatically outperformed California in terms of infections, hospitalizations, and deaths (all while protecting jobs and the tax base and respecting individual liberty).
How can this be, with Florida largely open while California continues to lock down? Could it be that everyone in California is ignoring the rules? If that was the answer, wouldn't the result be equal to FL, not worse?
Could the restrictions in California be making things worse by forcing everyone indoors, where most transmission occurs, and increasing the general level of panic and hysteria?
Or, perhaps, is California just in the midst of a regional Covid season which all their masks, and lock downs, and stay at home orders could not impact?

Given the similar patterns in Nevada and Arizona, it appears that the regional-seasonal explanation is most likely true.
In other words, when the local coronavirus season arrives, shutting down gyms and restaurants and closing parks and mandating masks - none of it appears to make any difference, despite the desperate belief that we can control an endemic respiratory virus.

Four days ago, Oxford University published a report on US state government responses to Covid-19, showing a wide divergence in relative stringency with that divergence growing over time as 1/2 the US states open up and 1/2 continue to lock-down:
This study, if anything, understates the differences between states as I have personally visited 20 states since this Summer and the day-to-day experiences in Alabama or Idaho vs. Washington or Nevada are dramatically and obviously different.

The obvious question is: have the stringent states bought anything with their authoritarian limits on personal freedom?

Looking at cumulative Covid deaths, there is no clear correlation between stringency and mortality:

Euromomo.eu shows excess mortality in the Spring more than 2X that seen in the fall, despite wider spread:
Similarly, the CDC estimated excess mortality in the Spring was about 2X that seen in Summer or Fall, despite ever widening spread:
Why has Covid become so dramatically less lethal over time? One primary reason is that doctors are no longer actively mistreating patients:

It has now been 4 weeks since "cases" peaked in the northern Great Plains states; they have now fallen nearly 50% since mid-November despite mild restrictions and limited mask mandates:
Cases in the Rocky Mountain states appear to have peaked one week later (before Thanksgiving):
The southern Plains states seem to have hit a plateau before Thanksgiving and may have begun their inevitable descent:

Officially, the CDC shows 335K excess deaths in 2020. But, something is very wrong with their baseline expected deaths. For some reason, they "expected" mortality to decline this year - after steadily increasing annually for the past decade:
If the CDC had simply extended their average expected deaths trend into 2020, excess deaths would be reduced by 114K. In other words, about 1/3 of CDC reported excess mortality is due entirely to an artificially low baseline:
To paint this in the best possible light, I believe the CDC may have reduced expected 2020 deaths because of the extraordinarily mild Winter deaths observed in 2019. However, past trends indicate that low mortality years tend to be followed by high mortality years.

In the USA, for those under age 45, lockdown deaths exceed Covid deaths by nearly 2:1, through the end of August.
For those aged 45-74, lockdown deaths account for 23% of net Excess mortality; mortality displacement explains (at minimum) a further 24%.
For those older than 75, mortality displacement drove 26% of excess mortality and lockdowns drove a further 18%.

Why are so many elderly dying of Covid? Mostly because those are the people who die, of any cause. Past age 45, Covid share of total deaths is fairly constant. Under 45, Covid mortality is vanishingly rare:
Across all age groups, Covid is rapidly disappearing as significant cause of mortality in the USA. This could be both because Covid deaths are declining and because lockdown-induced mortality remains high.
For those under 15, the risk of dying with Covid are literally 1 in a million while almost 1% of the 85+ group has died with Covid. To put that in perspective, 11% of those over 85 have already died this year, from any cause.
