Holy shit. I'm a lurker as a rule, but have to speak here.
My wife is the same - 100% emotion, 0% logic. Hates Trump with a passion because that's what the Democrat party told her to do. Can't even have arguments, she just wants to hate.
Example - yesterday she sees a picture of DJT's cuffs with a 45 on them, says "Oh my god, what a narcissist." I say "really, more of a narcissist than a guy who literally names his dog after himself?" She says "yes," end of discussion.
Like you, I love her regardless, and we have kids so leaving isn't on option. I can only hope we have some public reveal soon - that's my only hope for a marriage that survives our kids leaving for college.
