The most basic question that the Trump presidency raises is: How the hell did this happen?
There is, obviously, no single answer for why this particular miscreant became president of the United States. Were it not for the Russians or WikiLeaks or James Comey, etc., etc., we might still resemble a normal nation. But these isolated explanations do not speak to the larger question of how this jerk got anywhere near the White House in the first place. In the past few months, three authors have sought to address that larger question, and with them, we can begin to see an outline of how the GOP allowed itself to be taken over by people with only a tenuous grasp of reality.
