A near impossible literacy test Louisiana used to suppress the black vote

In many parts of the world voter registration is a perfectly normal practice and no one challenges it. The biggest reason for having it is that it disallows voting multiple times.

What in your opinion makes the voter registration disenfranchising for voters?

It's an additional step that must be completed well ahead of election day, making voting a two-step process. It shouldn't be necessary: you can determine on election day whether someone's already voted or not before they cast a vote.

Can you suggest a specific mechanism to do it that would be transparent to the public?

I don't know about the US specifics but in Russia people voting multiple times was the main strategy of fraud in 2010s (that is before they gave up all the pretence). Before this scheme came into being, the system of isolated voting points where every action was observable and verifiable based solely on the local context had worked reasonably well, to the displeasure of authorities.

That requires some preparation. Example: in Italy the state knows where everybody live (this is self reported but it could be inferred in many ways) and, more importantly for this case, where everybody has residence (that might not be the correct English word, sorry.)

I could have residence in a city because I was born there but I could live in another one because for one year I have to work in that other city. But I don't sell my home, terminate contracts with utilities etc, also because maybe I go back home once or twice per month to visit friends and parents. Ok, so when I have to vote I do it in my city of residence, in a given place and not in any other one, and I have a card that I have to present together with my photo id. They have a register with the voters that are expected to vote there and they check my name on the list, stamp my card, give me the ballot.

Note that this is a process that starts when one is born and keeps going through all the life of a person. It's quite an effort but it makes participating to elections very low effort for a voter. If we had to register to vote... Who would vote, only very interested people. It's amazing that so many people vote in the USA given the process.

The problem isn't necessarily voter registration per se, but how easy or hard you make it. Giving politicians or bureaucrats the power to disenfranchise voters by requiring jumping through seemingly arbitrary hoops or based on vague rules will always lead to abuse.

In many countries if you are a citizen (or permanent resident, depending on the election), old enough, and registered as living in the country you are automatically registered to vote. No need to do anything, your form shows up in the mail before every election. The only times you might have to do something is if you've very recently moved to a different part of the country or if you live abroad.

You should apply a large permanent mark to people that already voted. It must last one day or so. But that could infringe the right of not to vote, unless voting is mandatory. Or make impossible to vote twice because everybody is tied to exactly one anonymous ballot. See my reply to parent, about the voting system in Italy. However if some party control a part of the voting system, they can do whatever they want in several ways. For example vote with the ballots of people that didn't go to vote. In my country they'll have to get the photo id number of those people but it's not difficult to get if they have access to official data.

Some time ago every election or referendum simply put a stamp in the passport when voting, but that was before plastic ID cards. Now they have an online verification process before handing you the ballot papers; this also reports your ID for the invalidation of any pre-election votes (e.g. mail-in ballots) elsewhere.

Merely requiring photo ID is controversial in the US (and not done in MA where I vote).

Additionally having a continually up to date registry of persons would definitely not fly here.

Millions of voting age Americans do not have a non expired photo ID.

I wonder how that compares to Italians.

You used to need a passport to vote? 42-47% of Americans have passports currently. In 1990, only 5% of Americans had passports.

Going from memory:

In Italy you're meant to always carry a valid, officially accepted form of ID (and as far as I know, only ID card and Password fully qualify, but driving or nautical licenses, gun permits, and some forms of railway employee ID are also generally accepted as they're ultimately made by the government) and it's a crime (with up 2 months in jail, though it's usually just a fine) to refuse to show it upon request to on-duty "public security officials" (Italy has a bunch of entities in addition to the normal police) and in a few other rare categories (a bus or train inspector has the power to demand your ID if you're travelling without a ticket and need to be fined).

If you don't actually refuse, but you explain you just forgot your ID at home, you can still provide your details verbally and are usually allowed to go, and "invited" to show your ID within XX days at any police post. But if you were driving a car, there will be a small fine anyway.

If the officer has any suspicion you lied, or that your ID is fake, you can be taken to a police station for identification.

....ahem, obviously I meant Passport... not Password...

It requires you to take time to register, either out of your days beforehand to be registered day of; or time out of your day to register to vote at the polling place day-of. This is on top of having to drive potentially a ways to get to the polling place, only to be told you cannot vote because you're unregistered.

It should be a national holiday, or you should be able to vote online. Session IDs would go a long way in preventing voter fraud, I think.
