I can't anwser that one.....I am no longer in state and to be honest I think this might be the first time Ohio has done early voting. I don't remember ever having the opportunity to do this in all the years I lived there.
So, I'm pinging LS and Ravi with this reply to you. They're both doing a lot of heavy lifting on this info and they might be able to answer your question.
Early voting is considered a part of absentee voting in OH only. It is separate in other states but for some reason they lump it together with absentee voting in OH. Don’t know why. Great job LS btw.
We did early voting last year for the first time. BTW, spoke with the count co-chairwoman today. She isn’t ready to call it for Romney, but said in our county we registered MORE in August than the Dems, and that their “register/same day vote” was a huge disappointment. They had 1400, but expected thousands. They had a three entire floors with folding chairs set up that were empty. She thought our organization was very good.
