What should turn your blood cold is that the people you mention, particularly Pelosi and Hillary actually have minds operating at a high cognitive level. They know exactly how to manipulate their base almost into a killing frenzy. You’re average lib is fairly addled in the abstraction and logic department but their leaders are manipulative geniuses.
I really think you’re wrong about P and H. I think they’ve long passed the point where they’re improving cognitive function. At this point, I’d bet that they’re working on some level of instinct and that they’re being directed by staff, as Jarrett directed Obama. P and H still have the egos, so the manipulative skills are in the people working for them rather than in themselves.
