Trivially simple to do for anyone organized*, given most states have both voter registration records and records of previous voting available on request, or easily downloadable from whatever the latest iteration of Raidforums is even if they aren't 100% public. All you need to do is find ten or twenty people of your gender within twenty or so years of your apparent age who haven't voted in the last couple elections and drive round voting as them. If you skew older, noone's going to bat an eyelid if you act confused if you get unlucky and are told you've already voted.
* anyone invested in either wing of the American two-party jew-party queer-party system is too stupid to do this, obviously
