The electorate is also slightly more liberal, more African American and slightly less evangelical than four years ago.
All of that is good for Obama.
At the same time, the state is slightly less optimistic about the future of the economy than the nation as a whole and is more apt to say that the government does too many things than say it should do more to solve problems — a view more in line with Mitt Romney's campaign.
All of the numbers will change, of course, as later exit polls roll in. And Republicans like to think that their voters tend to show up to the polls later in the day.
But if Obama's favorable rating among voters remains much higher than Romney's, it's going to be difficult for Romney to win Ohio and, by extension, the presidency.
