Unfortunately in politics perception is everything. Thus politicians most often don’t appeal to intellect for persuasion, they aims to convince one’s crude ego emotions of their message.
They find a story line that they think a certain group would perfer to believe, then try to support it for advantage. Ego emotion is juvenile, silly and relentlessly insistent. It is impervious to facts and reality.
One of Hitler’s henchmen said about Adolf, seek him out with your heart not your head.
