Weiser’s argument doesn’t prove as much as she’d like, because it’s also true that it’s in swing states where there’s the most reason to worry about fraud. It’s a corollary to the old saying “if it’s not close, they can’t cheat.”
If there was any evidence that in-person voter fraud existed, this might even be relevant. But, of course there isn’t. And it doesn’t even make sense in theory; you can’t swing an election, even a relatively close one, by mobilizing fake voters. That’s not how elections are ever stolen. ID laws aren’t about stopping voter fraud; they’re about making it harder for people who don’t reliably vote Republican to vote.
