Few people ask where politicians obtain their insights, ideas and policy positions. More should. When the current minority leader HOR, and former majority leader HOR, stated, "we have to pass the bill to see what's inside" and the individual politicians base their policy votes on the testimony of industry captains and fed economists, I hardly call the politicians independent or objective.
Politicians are mostly mouthpieces for constituent groups and don't understand any of the laws they pass at the granular, much less atomistic level. Their briefs, talking points and speeches are all prepared by others.
The individual can only be as smart as his information input and analytical framework.
