The criticism some of us have of those who are obsessively anti-Trump isn’t that they are necessarily wrong about the president. I personally share many of their harsh assessments, especially of his fixation on petty feuds at a time of international peril, not to mention his overall temperament.

Yet they can also be almost naive in their evaluations of politicians and government pre-Trump, blind to how the governing class’ failures and character flaws made this presidency possible in the first place. Indeed, they often risk becoming the resistance that cried wolf.

Nothing Trump does wrong can be excused by pointing to the Clintons or others. We don’t want bad precedents to be set by the president or followed by future ones. What we should want is for all politicians to abide by the same set of rules — whether we like them or not.
