Even though Donald Trump’s poll numbers continue to be abysmal, there seems to be something of an anti-anti-Trump backlash underway in GOP circles. Never-Trump conservatives have never been a particularly robust group and their numbers seem to be dwindling by the day. Now, they are taking friendly fire. Even the venerable Trump skeptic David Brooks suggests in The New York Times that Trump critics have not only gone too far in their opposition, but actually seem to “be getting dumber.”

While Brooks appears to be reacting to the Michael Woolf’s journalistically challenged best seller “Fire and Fury,” he is echoing a growing refrain on the right: If you ignore Trump’s tweets and other erratic utterances, his presidency is really not all that bad. (Brooks wrote his column just days before Trump referred to African countries as “shitholes.”)

The argument from Brooks and other Trump rationalizers is actually quite plausible: Under Trump, the GOP has been able to pass sweeping tax reform, eliminate the individual mandate, roll back the regulatory state and install conservative judges throughout the federal judiciary, including, most notably, the Supreme Court. The stock market continues to soar, unemployment is down, and the excommunication of Steve Bannon could mark a turn toward a more normal presidency, with rational and prudent center-right figures now steering the policy ship.

In his recent column, Brooks argues that it is “almost as if there are two White Houses.” There is the reality television White House and “the Invisible White House,” which is quietly effective “at managing around the distracted boss.”

In this telling, it is not the GOP that has surrendered to Trump; it is Trump who has essentially ceded policy to mainstream conservatives. Trump’s lack of any fixed principles and invincible ignorance on policy means that he is an empty vessel that the establishment GOP can use to accomplish many of its dearest objectives.

In this telling, it is not the GOP that has surrendered to Trump; it is Trump who has essentially ceded policy to mainstream conservatives.

Indeed, it seems the publication of Woolf’s book has actually emboldened some of Trump’s new defenders, who point out — correctly — that the book’s overstatements and shaky relationship with the truth serve to weaken more reality based critiques of Trump’s presidency.

Ironically, by raising questions about Trump’s basic mental fitness, the book has also encouraged some in the media to lower the bar for Trump. At a meeting with congressional negotiators on immigration, for example, Trump was clearly unfamiliar with the details of his own position on proposed legislation. But, expectations were apparently so low for the president some reviewers passed over his ignorance and praised him for his coherence.

Here is the problem with that perspective: You don’t have to think that Trump is crazy or suffering from pre-dementia to recognize him as a dishonest, erratic, narcissist who is demeaning the presidency and potentially rendering conservatism toxic for a generation. We absolutely should beware the kind of mindless oppositionalism that lowers our intellectual and journalistic standards.

But to regard Trump’s presidency as normal, or something approaching normal, conservatives would have to ignore:

The president’s many rationalizers would like to believe that objections to Trump are merely matters of taste or style or the president’s “personality.” But as this list (which is hardly comprehensive) suggests, the objections are far more serious. Even with tax cuts and Neil Gorsuch on the Supreme Court, the Trump presidency continues to pose a moral, political and perhaps even existential challenge to conservatives. That has been true from the beginning and there is no sign that will change anytime soon.
