Obama and his allies had violated the norms so often for their policy goals that they couldn’t afford to be replaced by anyone but one of their own. The more Obama relied on the imperial presidency of executive orders, the less he could afford to be replaced by anyone who would undo them. The more his staffers lied and broke the law on everything from the government shutdown to the Iran nuke sellout, the more desperately they needed to pull out all the stops to keep Trump out of office. And the more they did it, the more they couldn’t afford not to do it. Abuse of power locks you into the loop familiar to all dictators. You can’t stop riding the tiger. Once you start, you can’t afford to stop.
