If President Donald Trump is a budding authoritarian, as his critics allege, one of the safeguards is Judge Neil Gorsuch.

For all that Trump has flouted norms and gotten off to an at-times amateurish start in the White House, his pick of Gorsuch was extremely normal and highly professional. The Gorsuch nomination is exactly what everyone should want from a President Trump, especially those who most fear and loathe him. Yet Trump’s fiercest opponents began denouncing Gorsuch immediately.

This is the dilemma for Democrats: Either Trump is a threat to the republic because he doesn’t appreciate the Constitution and is bound to violate it with excessive assertions of executive power, or Gorsuch is a threat to the republic because he has an overly punctilious view of the Constitution that entails, among other things, a dim view of executive overreach. Both can’t be true.

If Democrats really believe that Trump is as dangerous as they say, they should think of Gorsuch as the equivalent of Gen. James Mattis. He is a responsible choice from what they consider an irresponsible president, and they should embrace him on those grounds. Gorsuch is the opposite of Trump in every way that should matter to the president’s enemies.

If they hate Trump because he’s anti-intellectual, Gorsuch is a Harvard-educated lawyer who is widely admired for his acute analysis and writing.

If they worry that Trump has shown little regard for the Bill of Rights, Gorsuch is a stickler for it, including the Fourth Amendment that will be the foremost obstacle if Trump’s law-and-order agenda goes too far.

If they fear federal power under Trump overawing the prerogatives of states and localities, Gorsuch is a devoted friend of federalism.

If they are anxious about the Trump executive branch trampling on the other branches of government, Gorsuch calls the separation of powers "among the most important liberty-protecting devices of the constitutional design."

Why won’t Democrats follow their anti-Trump reasoning and support Gorsuch?

First, there is sheer partisanship. They believe the Antonin Scalia seat has been "stolen" from them because Senate Republicans refused to act on the nomination of Merrick Garland.

Second, Democrats don’t truly oppose Trump on procedural or constitutional grounds, and so have no use for the likes of Gorsuch. Liberals didn’t object to President Barack Obama’s executive orders unilaterally rewriting immigration law, or recoil when he was repeatedly shot down 9-0 by the Supreme Court.

Third, the left cares about social issues more than anything else, particularly the judicial imposition of the current abortion regime. If Gorsuch isn’t on board, it doesn’t make a difference whether he will be a presumptive check on the president or not.

Finally, Democrats are getting sucked into the politics of the primal scream. They are heading toward all-out war against Trump, in which case all that matters about Gorsuch - or anyone else - is that he is associated with the president. The best way for Trump to overcome this unhinged opposition is to make choices as sound as he did with Judge Gorsuch — an unassailable pick being assailed by people who profess to yearn for sobriety and traditional norms, even as they reject both themselves.
