Given recent events, it seems clear we need to rethink the role of the executive branch, probably to strengthen gov't services (e.g. cabinet-level agencies) and make them more independent of political agendas and misdirection. A more independent EPA, NOAA, FDA, law enforcement, military, etc that are governed by strict codes of conduct and missions that proscribe their misuse by either a careless/malignant POTUS or legislature could save many lives, make US policy more stable and sustainable, and upgrade the standard of living for more than just Americans.
I think we need to do more than just vote.
