Tuesday, March 4th is of course election day in Ohio. There is no way that you could not know this, from the yard signs to the phone calls to the television and radio ads and everything else.
Just a reminder though, that you do need your photo id to be able to vote. This is a relatively new requirement and unless you voted in November you may not be aware of it.
