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.
Especially disgusting when people show up to vote, aren’t registered, are instructed to cast a provisional ballot, then are still faced with (potential) jail time for not being allowed to vote.
