Probably less to do with illegal voting, more to do with polling places being understaffed and city/county/state shenanigans requiring 2 forms of photo ID, your birth certificate, and a letter from your Second Grade teacher saying you're a special kid.

Do early voting next time!

And vote so there is a next time.

Probably cause they won't let you vote more than once in the same place. You gotta find other polling places.
