They’re asking election administrators to use their data to purge voter registrations, which means names could be removed in a less public process than a formal voter challenge. The strategy could mean electors won’t be summoned in advance to defend their voting rights and the identities of those seeking to purge voters might not be routinely public.

The books spends more time making him a statement how various conservative legislatures are trying to purge. It talks about what areas they’re trying to purge voters from and explores multiple areas. I felt like it was a pretty good read not saying it’s 100% correct but a lot of things kind of make sense.
That being said a quick Google has sources saying it didn’t affect the outcome I find it very disingenuous to be expelling voters in good standing while using cheesy junk mail style notifications. If you’re really concerned about getting the voting lists all cleared up fine but do it in a transparent method no underhandedness.
