Some people in the US are quite upset about voting fraud: people who can't legally vote (by reason of non-citizenship, death, fictionality, etc.) are on the voting rolls, and sometimes actually vote. Other people in the US are quite upset about voter purging: people who can legally vote being removed from the voting rolls.
In many cases this is political: one party benefits from removing legitimate voters of certain characteristics (viz. those associated with non-citizenship). The other benefits from spreading voting as widely as possible, even to the occasional non-citizen.
But actually, both sides have their points. Political opportunists aside, there is general agreement that, ideally, the voting rolls would contain precisely the people who the laws say can vote.
But there's still stuff to think about, and even mock.[Poll #1867298]
