a big question with all of these stats is whether or not they follow precedence, because there is almost certainly some amount of the voter base that will experience these issues, whether due to skill issues, or unfortunate mishaps. This wouldn't nullify the claims, because disproportionately targeting certain voter blocks would definitely constitute a huge problem, but that's a large uphill legal battle that needs to play out.

one of the arguments used is that "these laws passed in states where trump won" and to a degree that's probably true, could be for any number of reasons, but the deep red states were never going to vote blue, so a lot of this is almost certainly going to be a sort of survivorship bias fallacy, where you're surprised by red states restriction access to voting, and then voting red. Realistically it probably doesn't make a significant difference, maybe it does in the swing states, it's harder to tell unless you have the data.
