OK, so earlier I tweeted a chart of internationally fully-vaccinated rates, and wondered if someone had split the red and blue US states.

And then I did it and @ritwik_priya wondered if this was an income effect. So I investigated! 1/

Here is the red-blue split in fully vaccinated (FV) rates by time (lefthand side - incidentally, it is depressingly easy to sort the states - very few toss-ups)

But then I looked at GDP per capita and compared to latest FV-rate 2/

... and you can see a *rough* correlation. The slope of the chart says the FV rate rises 0.5 ppts per $1000 of GDP per capita.

So *then* I split that out, i.e. measured the distance from the sloped line, and compared Democrat and Republican states. You get this: 3/

The Democrat states are 5pts above zero, the Republican ones 5pts below

I am sure there are plenty of other variables. Education levels? But the initial impression still stands ... 4/4
