I think that OH-02 now has more of Cinci than it used to (so as to shore up the OH-01 a bit), but Schmidt usually ran well in the Hamilton County portion of the CD (her home is just across the Cleburne County line). Schmidt was usually weakest in the rural counties closer to Portsmouth than Cinci, and Wenstrup probably did well there despite being from Cinci. In the end, though, Wenstrum won on the issues (cutting government, etc.), not due to geography.
Well, my intuition was off by 180 degrees. Wenstrup won huge in Cinci and carried Clermont, but Schmidt actually won all of those rural counties that normally gave her trouble. I guess that Wenstrup didn’t advertise outside of the Cinci market. http://vote.sos.state.oh.us/pls/enrpublic/f?p=130:15:0:
