You can see that counties that were enthused for Obama 2008 took a little break from liking Joe and The Ho in 2020.
Oddly, only 9 of the 86 Minnesota counties came out like gangbusting berserkers for The Joek.
Kind of nice for state-stealing when your ballot-harvesting area is a small 55 mile by 70 mile rectangle...
Those efficient people from Minnesota!
