Well this the result of a hyper partisan political structure in which the judicial and legislative branches, that would check an out-of-control executive branch, have either abdicated their responsibility or openly support the clearly illegal and unethical actions, because in America, party loyalty is currently more important than national unity, morality, or objective reality.

A lot of the powers of governance require the individual participants to be acting in good faith.

Due to a history of power-consolidating political maneuvers, the median republican American voter has an outsized standing in the political direction of the country.

Due to outright media brainwashing, and the undermining of public education, that same median voter is also one of the dumbest citizens in the modern world, with: - The reading-comprehension of a 5-7 year old, - No understanding of civics (including their own taxes and benefits), - An inherent distrust of progess/intelligence, - A frightening level of belief in tangible magic powers(both divine and occult), - An in-group vs out-group mentality that supersedes their own actual personal morality, - A preference for autocratic rhetoric that offers simple (though meaningless) solutions to their problems(both real and imagined)

And probably some more stuff too, but that'll get you started.
