Ah, I understand. I was thinking in terms of alliance webs, not individual political beliefs (and/or personality traits). In that case, I don't think there's a need for centralized info on it--though I do think a way to flip through character backgrounds that you've done research on in that particular playthrough would be nice. Speculating on those things from your previous investigative work is what makes the most sense.
Okay, but now understanding what you're referring to--These would definitely be interesting stats to view in a debug console? If you have plans to include that, similar to LLTQ (and LLTQ's cruelty, noble approval, commoner approval). But which tags apply to which people feels like something I would go to a wiki for, rather than expect it to be presented in game
