Hatred for Trump has nothing to do with it. Liberals have always fetishised "reaching across the aisle" as they call it. And they have to rationalise that GOP is a grave threat to Americans (especially the women and minorities they love to hide behind) yet somehow it also needs to exist. So they like to imagine that there are sects within the party that are reasonable and they rehabilitate hellspawns like Bush and Cheney who have long since retired from direct bloodletting.
