Sure there are limitations everywhere, but in my country for example there are no voting districts or other constructs. No restrictions on who can vote, even with an expired passport or other ID you're still allowed to vote. And no queues at the polling stations, there are enough and they're equally spread (let's not even start about the ridiculous "water" rule in Georgia).

At the end of voting day they do something you would expect everywhere: count all votes the same. And then whoever got the most votes has won. I think the US would really benefit from a system that's more like "everyone can vote, most votes wins".
