In Sweden, does getting your state-issued ID so you can vote require visiting a government office that is only open during business hours on weekdays, in a place very poorly served by public transit and far away from poor neighborhoods, so that poor people without cars will have to take a whole day off from work to travel there? Is the office understaffed so it might take two or three visits to actually get your ID? In Sweden, when the government reduces the number of places you can get ID or cuts hours under the guise of cost cutting, does almost all that cutting only come from offices that serve high minority areas?

In Sweden, are there limited protections for worked so that many poor workers won't have any paid days off they can use for such a trip, so it will cost them a day or two of pay to get their ID, and perhaps their job if their boss doesn't approve of them taking time off from work?

In Sweden, are the politicians who instituted the voter ID policies the same politicians that have drastically reduced the number of polling places per capita in minority neighborhoods so that actually voting there can require hours of standing in line (and missing work if your employer doesn't give you a paid day off to vote), while not cutting or even increasing polling places per capita in white neighborhoods so that it is a breeze for whites to quickly and easily vote?

Have they cut back early voting programs that opened the polling places during the weekend before election day, so people could vote on their days off?

If the answer to all of the above is "no", then what you see in Sweden is pretty much irrelevant when it comes to understanding voting in the US.

The fact is that the people enacting voter ID laws in the United States (1) are generally the same people who have been working hard to limit minority voting, (2) cannot demonstrate that it solves any actual problem, (3) try to make it hard for poor and minorities to get the ID that they pick for their system while making it easy for white people.

That's why there is plenty of opposition to voter ID--the politicians pushing for it are not acting in good faith. If someone proposed a voter ID system in good faith--one in which it was free to get ID, could be obtained quickly and without the need for a lot of travel, and was easy for minorities to get as for white people, there would mostly only be objections from those who oppose national ID system in general.
