If you are using an absentee ballot to vote in the upcoming presidential election, NOW IS THE TIME!
If your ballot shows up late, it probably won't be counted, but there's nothing wrong with sending your vote early, so get a move on!
LOTS of things will slow the mail down as the election approaches (some of them natural, some political), so don't wait. You don't have to have the ballot in hand to decide who you will vote for. Send off your absentee ballot request NOW.
(Note, the deadline for absentee ballot requests is October 31, but you probably shouldn't push it. There's no reason to delay because you aren't committed to anything when you submit that request.)
And remember that Ohio absentee ballots need two stamps.
