Because of the way OH treats party registration, the numbers are not as impressive as they look. That said, there probably is an increase in the percentage of the electorate that is R over 2008. I don't know how much, but I'd guess about 2-4 points.
Is that reflected in the polls? I don't know.
Yes, that's true. Suffice to say it is likely that Romney will get the vast bulk of the vote that voted in the GOP primary this year. That itself gets him 22% in the most Democratic county in the state.
I think that is pretty much the case and that the OH electorate will be more favorable to Romney than it was to McCain.
