For months I've been posting weekly looks at the rate of COVID-19 cases & deaths at the county level since the end of June, broken out by partisan lean (i.e, what percent of the vote Donald Trump received in 2020), as well as by the vaccination rate of each county in the U.S. (nonpartisan).

This basically amounts to the point when the Delta Variant wave hit the U.S., although it had been quietly spreading under the radar for a few months prior to that.

Now that we're several weeks into the Omicron Variant wave, I've decided that it's time to update my case/death rate tracking to reflect that as well...because the data so far is showing a completely new chapter as we enter the 3rd year of the Coronavirus Pandemic.

The "start" of the Delta Wave was fairly easy to lock in, at least for my purposes, because thanks to the initial vaccination surge, both cases and deaths from COVID had dropped off dramatically right up until around the end of June. The Delta Wave started showing up in the daily deaths pretty quickly as July started, as shown below.
