How many millions of 18-year-olds are in America who'se data is available through public schools, healthcare centers, to illegally register people to vote who will not vote. But there will be a vote cast in their name, and they'll never know, because they'd never go look to see if they'd voted if they weren't registered themselves.

How many millions of 18-year-olds will appear registered to vote, and cast ballots in this election, who never registered themselves to vote?
