DeWine will win because Southwest Ohio will come through for him.
Brown might win Cleveland, Columbus and Dayton, but he won't win outside of 5 counties within the state at most. Yes that includes those dirty hippies down in Athens :)
"DeWine will win because Southwest Ohio will come through for him"
Probably true, but in most other years, but not true this year.
Dewine has ticked off many people here over things such as abortion, 2nd Amendment rights, the "Gang of 14", etc. etc.
I will be voting for the Democrat, and many (R)'s I know are either going to be doing the same, or not voting for either.
Brown won't win Montgomery County. We were a draw for Bush in 2004, and he ran ahead of Bush. This is a DeWine win.
Brown will probably also do worse in Dayton than you might think. Wright Patt Air Force Base has a big effect on the area, and Brown's views on the military and it's use aren't going to be very popular with a large portion of those living there.
