Ohio?
You missed all that?
Is that not where you reside?
I guess it's possible, depending on your news outlet of choice...
Register and get your early ballot at the same time, cast your vote and leave.
Go to the next precinct and do it again.
Drive to the next county, and do it again.
They hand you a ballot, you drop it in the box and leave.
If they later disallow your registration, so what?
They can't throw out your vote because the ballot is anonymous.
