21 to 12 isn't a 2/3 vote. What is required for an override in Ohio?
In Ohio it only takes three-fifths to override (for most things -- apparently there are some situations that require two-thirds, but it looks like this wasn't one of them).
three-fifths according to Ohio Constitution:

They needed 20.
