Author Charles Gabs then found the death rates by county and compared those rates to the fractions who voted for Donald Trump.
Before 2020-11-04: (10%-step bins, per 100K population) 90.9, 109.1, 98.4, 71.7, 70.1, 56.3, 52.5, 53.8, 48.3, 48.0
"As you can see, the death rate in the bluest areas of the country was as much as 2.3x higher than in the redder counties nationally. Most of this is due to the massive, ugly first wave in New York, New Jersey and other Democratic-leaning states back in March/April 2020."
The author then split the post-election time in two, using June 30 as a dividing line because (1) the Delta variant emerged around then and (2) FL and NE stopped publishing per-county data.
From 2020-11-04 to 2021-06-30: 75.9 78.1 101.8 94.9 102.9 108.7 132.2 151.0 169.4 202.2
"As you can see, from Election Day through the end of June, the situation completely reversed itself: The COVID-19 death rates in the reddest counties began to run higher than in the bluest counties...as much as 2.66x as high, in fact."
and "That leaves perhaps 229,000 potential U.S. voters who died between 11/04/20 - 6/30/21." He estimates 87K D, 124K R, and 18K independent/swing voters. Meaning that 37,000 more Republican than Democratic voters died nationally.
From 2021-07-01 to 2021-09-07: 3.7 5.4 6.1 7.9 11.5 12.6 17.0 22.2 25.9 27.7
That's 3.3K D, 17.1K R, and 1.3K I voters -- 13,800 more R's dying than D's over the last two months.
As for Nebraska and Florida: Again, I'm reluctant to include this in the table above, but if you put a gun to my head I'd say the "net GOP voter deaths" since 6/30 would be around 4,000 higher if both of these states were included; call it perhaps ~18K more GOP than Dem voters having died of COVID since the end of June.
If so, that'd be a total of perhaps 55,000 more so far this cycle (~146K GOP, ~91K Dem, ~20K Swing/Indy).
What will happen between now and November 2022? The author assumes 150,000 more deaths, divided up 80% R, 15% D, 5% I.
The grand total would then stand at somewhere around ~105,000 Democratic voters, ~220,000 Republican voters and ~26,000 swing voters having died nationally between 11/04/20 - 11/08/22...or a net loss of perhaps 115,000 more Republicans than Democrats overall.
Now, you would think that this would cause Republican leadership to be deeply concerned...but they clearly aren't.
