I understand why the Founders wanted split, head-butting government. What they didn’t realize is that once the scum become established in power, the inherent sluggishness keeps them there. Of course, professional politicians were not foreseen back then. What we need, and will never get, is congressional term limits. Hey Reps, the presidency is term limited. Why aren’t you?
IMO it’s the consolidated national media that is the source of the problem you address.
The Founders never imagined that such a unified movement to distort reportage from DC would arise- because they never imagined TV.
People hear of politicians and events in DC as this media describes them. Politicians that make the media happy (IE: help their profits) have cheap, easy re-elections.
