They don’t have to prove that someone is not a qualified elector to disenfranchise them, throwing up barriers to make it very hard / impossible to vote is enough. In the past the federal government could intervene if something like that happened, but that’s not really possible anymore thanks to the current scotus, so it’s up to the states.

And this state is now laying the legal groundwork: If “every” persons with xxx qualifications has the right the vote by law and new measures get implemented that make it practically impossible to vote for certain people that fit those qualifications, then those people had a right withheld from them.

If “only” persons with xxx qualifications have the right to vote by law and new measures get implemented that make it impossible to vote for certain people that fit those qualifications, then … nothing. That’s the difference between “every” and “only”. Changing the wording to “only” allows the state to legally pile on extra requirements and barriers.

Examples of groups of people that I’ve seen disenfranchised by state actions: Prisoners, felons who have done their time, college students, minorities, inner city people, military abroad. Some of these news articles will have been attempts that were not (yet) successful.

I haven’t read the full wiki article, but I expect those examples to be in here: …wikipedia.org/…/Voter_suppression_in_the_United_…
