To paraphrase Voltaire after he attended an orgy, once was an experiment, twice would be perverse.

A bruised Donald Trump announced a new presidential bid on Tuesday night, an invitation to double down on the outrages and failures of the last several years that Republicans should reject without hesitation or doubt.

To his credit, Trump killed off the Clinton dynasty in 2016, nominated and got confirmed three constitutionalist justices, reformed taxes, pushed deregulation, got control of the border, significantly degraded ISIS in Syria and Iraq, and cinched normalization deals between Israel and the Gulf states, among other things. These are achievements that even his conservative doubters and critics — including NR — can acknowledge and applaud.

That said, the Trump administration was chaotic even on its best days because of his erratic nature and lack of seriousness. He often acted as if he were a commentator on his own presidency, and issued orders on Twitter and in other off-the-cuff statements that were ignored. He repeatedly had to be talked out of disastrous ideas by his advisers and Republican elected officials. He turned on cabinet officials and aides on a dime. Trump had a limited understanding of our constitutional system, and at the end of the day, little respect for it. His inability to approximate the conduct that the public expects of a president undermined him from beginning to end.
