It's really quite sobering to look at these state vs. state comparisons and see... no recognizable pattern. I'm sure something can be teased out of the data, but if we're honest, most of our interventions seem to have not had much effect. Places with similar populations and weather (ie, Florida, California) and VASTLY different policies have broadly similar outcomes.
Infection and death rates show no clear pattern from red let-er-rip states like the Dakotas vs. blue lock-it-down states. Some places did horribly (MS, AZ) and others did great (UT, VT, MN, WA, OR) despite bordering places that did horribly. Some places with big cities did fine, others did awful.
There's really not a heroic story of anybody getting it right you can tell here, IMO. If I had to draw a lesson from this, I'd say that having the ability to test a lot, and the willingness to do COMPLETE lockdowns would be the best weapons for a future pandemic.
