it's bigger than that
My thinking, but in a different direction. I can't keep supporting a party that doesn't value what I do. I feel like I'm enabling them to be the lesser of two evils instead of really making them stand for personal responsibility and small government.
Usually I will vote republican, but sometimes I can't, for instance I voted for Mitt Romney, but not for McCain (not Obama either! lol).
I'll be voting Republican party line for all other candidates. I really hope Jim Renacci can unseat Sherrod Brown for instance.
I see it as Trump dismantling and remaking the party. If Dewine wins, he owes it to Trump.
Not that Trump is perfect, or that Dewine is up to snuff, but the party will get in line after victory.
If Trump loses, he can be written off as an anomaly, if he wins, both parties must change.
Not for DeWine, not after he claimed support for the Medicaid expansion. I have to draw a line there. I've seen too much the losers this enables.
