New York

who are not qualified to vote.
According to https://elections.ny.gov/enrollment-county, there are a total of 3.489 million registered voters in NYC.

800,000 would be about 23% of total registered voters. This number may not include any mail-in ballots.

Also keep in mind that there is only one week of early voting and there are fewer polling places for early voting than day-of voting. There were truly long lines for early voting and some people walked away. My friend decided to try another day when he was faced with a long line. When he tried the second time, he still waited about 90 minutes. This amount of early voting is unprecedented in NYC and the poll workers were left unprepared.
