Several months back DeWhine won his primary against a good conservative challenger. DeWhine got ~76% of the vote. The conservative challenger got about ~15% of the vote.
Maybe you heard two?
There were two challengers who did not get their names out. Less people voted in the primary on that issue than in others because many just didn't vote. It was like the voters wanted to vote against DeWine but did not know which of the two to vote for.
Today there is no enthusiasm for DeWine in Ohio. You cannot deny that. He is not one of us anymore. He is a Democrat in Republican clothing. Some Republicans may vote for him just to bolster the majority numbers in the Senate - but they are not voting for him. They will be voting for the "R" following his name. He is a RINO and undeserving of anything support. A man told me the other day it was worth having a Democrat senator for 6 years just to flush DeWine out of the system. The RINO is NOT Ohio's state mascot. That is why the Ohio Senate seat is in danger of being lost.
