I think the only conclusion worth drawing in Florida is that with Delta, you simply ran out of viable vectors for the variant, whereas with omicron, you have a perfect one-two punch of a six month immunology window closing for the vaccinated + naturally immune from the pre Delta wave and a novel and seemingly more virulent strain. I think the threshold for necessary social measures and government intervention to prevent spread were never truly exercised in this country and have zero chance of being socially, much less politically, viable now.I think there are so many variables that it makes drawing firm conclusions very difficult. What variant is spreading and what time of year it is dominant also plays a role.
Just look at FL recently. With the same mitigations, after the Delta spike it got to the lowest cases per 100k (swapping with Hawaii and 1 or 2 other states depending on the day) for several weeks. Then Omicron hit and it became one of the highest in a matter of days but still not as high (yet) as NY which has much more mitigation. Then you bring in the variable of the weather in NY is cold and in FL it is beautiful right now so people in NY are more likely to be gathering indoors vs. people in FL right now.
