Whether Trump stays in office or not, he has been the most consequential President of my lifetime, utterly changing the landscape of the courts, the laws, the institutions, and norms in a way no recent President has. Those who claimed he was weak were drastically mistaken.
Three Supreme Court Justices, fundamental long lasting reshaping of the Federal courts, a Muslim ban and a radically altered immigration regime, massive tax cuts for the wealthy, utter destruction of the environment and acceleration of global warming.
By constantly rotating those around him and in his administration, Trump showed how you could hollow out an administration and replace it with cronies and loyalists. He amped up already existing racist ideologies, and it will take generations to deal with what he has unleashed.
