Just show up with a cell phone bill and you're good to go. I mean, what greater proof of US citizenship/Ohio residency can there be?
Best part is they don't have to bother with all that pesky "registered for 30 days before casting a ballot" law stuff.
The Supreme Court was ruling on a petition [case materials] filed by voters who alleged that Ohio law required a voter to be registered for 30 days before casting a ballot. Although the court has not yet released an opinion explaining its reasoning, it concluded that voters must be registered 30 days before the election, rather than 30 days before applying for or completing an absentee ballot.
Yeah, yah gotta be careful explaining the reason the law is not the law. It can come back to bite ya.
