I am not convinced you use the same circuits for these two. I mean, if you mean politics in the sense "does a proposed law X make things better" then yes, but if you want to go deeper into ideologies and philosophies and trying to hunt down and slay the mind-killers, like, getting to the point where people don't get their panties in a bunch when they hear words like capitalism or socialism, you need to use more empathy driven circuits, mirror neurons...
