If you live in one of those two states, I’d suggest moving.
That said, if you can’t, while I’d hope you’d vote against them in the primary, as far as I’m concerned, in the general I’d give you a pass if you opt for them over whomever the Dems put up. Not that you should care about what I think.
I can’t/won’t move for various reasons, and if you saw my situation you would understand why. There’s no one to vote for. In the last election (as stated in an earlier thread) out of about 20 categories there were 2 I voted for, Town Clerk and Fence Viewer, both staunch conservatives.
