There are four groups of people who are typically not allowed to vote in the United States: children, criminals, noncitizens, and the clinically insane. This week, the bohemian voters in Takoma Park, Md., decided to enfranchise 16-year-olds and felons; the city council of New York is contemplating enfranchisement of noncitizens. And of course the Left also resists attempts to ensure that only those who are lawful voters are actually voting, by denying that there is such a thing as voter fraud — a nod to the clinically insane.
