He needs them to maintain his support.
It’s easy to survey the last 10 days in America and be flabbergasted at President Trump’s tendency to inflict politically bruising crises on himself. I know this because I had just that reaction on Wednesday, trying to make sense of his abrupt signing of an executive order intended to end separations of unauthorized immigrant families at the border. The current moment is more acute than others, but it follows the template set by the aftermath of a white-supremacist march in Charlottesville, Virginia; brinksmanship with North Korea; the collapse of Obamacare repeal; the firing of James Comey; and any number of smaller, half-forgotten crises. Why doesn’t he learn?
But maybe the truth is that Trump keeps creating crises because he needs them.
