Part of being rational is that ideally we can separate our beliefs from our feelings. I have conservative feelings (as defined by this article) but liberal beliefs (largely because I find that most smart people are liberals). If your beliefs line up with your feelings, that is a bit of a warning sign. (Although I suppose that if we just stick to two categories, there is a 50-50 chance that such alignment would happen by coincidence, so it's not much of a signal.) In my case, the fact that they go the opposite way is somewhat reassuring that I may be on the right track.
