What's kind of funny is despite winning the state Obama didn't do well in the bellwether portions of Ohio itself. Which kind of shows why using bellwethers to guess things is a folly.
That's not really true outside of the Southeast. Obama won almost all of the other bellweather parts of the state: Lake, Stark, Montgomery, Ottawa, and Hamilton Counties. The only remotely swingy county outside of the Southeast he lost was Clark, which is a bit of a stretch to call a bellweather anymore.
The Southeast is kind of my point though, for a Democrat to win the state and not there is pretty unprecedented. Especially winning
Hamilton County as well. I mean pre-2008 who would've been able to come up with a scenario where a Democrat wins Hamilton County and loses most of the Southeast.
