Well, for starters, those who are under 18 and are felons...
Plus... everyone else who either lives here and isn't a human, or "lives" here but isn't a "resident" are being excluded, too. People who work here, but don't live here can't vote here even though they might spend much of their lives here, people who are birds can't vote here, people who live in more than one place but are only allowed to register to vote in one of those places might not be allowed to vote here, and people who are illegal aliens aren't allowed to vote here, and even some people who just didn't have the resources to register weeks ahead of the election can't vote in that election, even if they wanted to.
