Many of these countries have a federal system -- the U.S. is not unique in this regard. In fact, switzerland makes our Federalism pale in comparison. Germany is more federalist. The U.S. is not unique in any way in having a federalist system.

Seriously, I need to keep saying this, but the U.S. is not special. We have no special insight about running elections that allows us to do it better than others. We do not have a monopoly on poor people. We don't have better healthcare, we don't have better police, we don't have better schools, or courts, we don't have better civic institutions more generally, and we certainly don't have better voting standards.

We should learn from the rest of the world and adopt best standards that work well across the OECD. Almost everyone in the OECD requires an ID to vote, and they have a better system, on average. We need to drop this irrational (and frankly, racist) notion that our citizens are unable to obtain IDs because they are too poor or dumb or too disorganized to get them.
