Next steps could include pairing an infrastructure bill with tax reform, eliminating budget sequestration and the debt ceiling, restoring funding to the State Department and cutting it to the United Nations, and saving the nuclear power industry through deregulation and federal subsidies — in the name of combating climate change.

But Trump’s move toward the Democrats on DACA — just as his earlier move toward them on the debt ceiling — isn’t about pragmatism. It’s not even about the plasticity of his convictions.

It’s about his addiction to betrayal, his contempt for those who bend their knee to him, his disdain for “losers” (especially when they’re on his side) and his desperate need to be admired by those who despise him most simply because they have the wit to see through him. This is a presidency whose defining feature isn’t ideology, much less policy. It’s neurosis.

In other words, there is no “pivot” at work in the presidency, in the mold of Arnold Schwarzenegger’s leftward turn during his governorship of California. There’s a mood swing.

That might comfort the Trump true believers who fear their president is abandoning them. It shouldn’t: He feels about as much loyalty toward them and their convictions as he’s felt toward his several wives. Remember that, as recently as 2012, he denounced Mitt Romney for an excessively harsh attitude toward immigrants, calling the Massachusetts governor’s policy of self-deportation “crazy” and a turnoff to “everybody who is inspired to come into this country.”

All of this is fun, since it’s always delightful to see blowhards and bigots get their comeuppance at the hands of their idol. The ideologues of the right are left to make do with their jester and his antics. I hope they have a sense of humor about it.

But there’s also a lesson for conservatives who mistook Trump’s bluster for seriousness. Not least among the conservative “Never Trump” objections to the candidate is that he would be a disaster to the Republican Party — not just because his beliefs, such as they were, were anathema to the party’s best traditions, but because at heart he was a destructive opportunist with no core convictions beyond his own immediate advantage.

The president’s newfound good sense on DACA is good news for the country, provided it lasts. Nobody should count on it whipping any sense into those conservatives who fell for him, also known as cucks.
