going to play devils advocate - in 2020 there was a competitive dem primary and this year there was not, they shut down opposition to biden. you have to be a democrat to participate in a democrat primary in most states (or more accurately, you automatically register as a democrat if you participate in their primary). its how you end up with things like thomas matthew crooks being a registered republican: he probably voted in the republican primary just to vote against trump. subtract all of the nikki haley voters and add them back to the dem column.
