DeWine beat his opponent in the same election by 25 points. Vance won by 7.
RDS beat his opponent that year by 20 point (a Florida record for a half century). Trump/Vance won Florida in 2024 by 13 points.
I know they are different races, and different electorates (you can spare the bandwidth)... but I'm not seeing this lack of electability that you are assuring me Vance is a force with but RDS lacks
DeWine is as smushy as it gets and is a pathetic rep for the R's but that plays in a state like Ohio during this time sadly. So of course Vance is much more in line with a traditional Republican on social policies will fare worse in the state.
