Politicians, in general (not all) are too blinded by ego to be aware of the needs and desires of those they claim to represent. It's just a fact. As a consequence, they become more focused on perpetuating the political structure they belong to rather than representing and fighting for the will of the people whose votes they solicited in order to gain their positions. It has become very pathological.
True, but some are far worse than others and Sasse IS a POS.
