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.
When official means exist to remove non-qualified voters, but groups like this want to circumvent that, it tells you they are acting in bad faith and is the whole reason they don’t want to do it the official/legal way. This should be grounds for election interference, voter fraud, and voter suppression charges.
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.
