Not all of the unrestrained anti-Trump zealots are progressives and Democrats. There are a lot of conservatives who detest him sufficiently to surrender their integrity, fairness and common sense as well. The Federalist’s Sean Davis has chronicled a revealing example: Washington Post pundit Jennifer Rubin.

Blogger Rubin is one of the rare in-House Post conservatives. Her 2016 columns regarding Trump were only slightly less vehement than mine, and once he was elected, she threw restraint to the wind. Before that, however, Rubin was one of the few reliably critical voices regarding President Obama and his feckless and bumbling Presidency.

One of the more frequent targets of her acid pen was the Paris climate deal. In a column mocking Obama’s “phony accomplishments,” Rubin wrote  that a Supreme Court decision on environmental regulations proved “how ephemeral Obama’s Paris climate change deal is.” Before that, Rubin  suggested  the accord was a cynical and transparent effort to take attention away Obama’s failure to deal effectively with radical Islamist terrorism, writing, “The president has no answer, so he goes to Paris to talk about climate change.”  Then she cited  the climate change pact as evidence that Obama and former Secretary of State John Kerry lived in a “fantasy world” where “a piece of paper”was a signature accomplishment “even if it achieves nothing.” Rubin accused them of selling the progressive base a “bill of goods” on the Paris deal, while Rubin called it “footprints in the sand.” Still later, Rubin cited approvingly Oklahoma’s Senator Jim Inhofe , the most infamous climate change skeptic in the the U.S. Senate, when he said that the Paris climate change deal was “devoid of substance.”

But Rubin really detests President Trump. For a man she hates to embrace her opinion is so unbearable that her only way out is to reverse the opinion. Before Trump announced that he was quitting the 2015 deal but had hinted that he would, Rubin transformed into a Paris accord booster, and declared that such a move would be a disaster. She wrote:

No, Trump’s pullout from the international accord would be a political act — one that signals solidarity with his climate-change denial, right-wing base that revels in scientific illiteracy. Being a climate-change denier — which entails dogmatic opposition to the Paris agreement — is a dog whistle to the far right, a snub to “elites,” who in this case include academics, government and private scientists, technology chief executives and others whose livelihood depends on accurate data. (Between “2013 and 2014, only 4 of 69,406 authors of peer-reviewed articles on global warming, 0.0058% or 1 in 17,352, rejected AGW [anthropogenic, or man-made, global warming]. Thus, the consensus on AGW among publishing scientists is above 99.99%, verging on unanimity.”)

This would also be an international dog whistle, reflective of Trump’s rejection of the Atlantic Alliance and the bonds of cooperation that tie Western democracies together. R. Nicholas Burns, a career diplomat, is quoted as saying, “From a foreign policy perspective, it’s a colossal mistake — an abdication of American leadership. The success of our foreign policy — in trade, military, any other kind of negotiation — depends on our credibility. I can’t think of anything more destructive to our credibility than this.”

How could President Obama be so wrong to sign what Rubin termed a phony pact, yet President Trump such a villain and a fool to repudiate it?

Simple: if Donald Trump does it or says it, it’s horrible by definition, and previous conclusions and analysis is inoperable.

Writes Davis,

What changed that could possibly explain Rubin’s complete reversal on the necessity of a deal she once said was “ephemeral,” “phony,” “fantasy,” and “devoid of substance?” Nothing. It’s the same deal today as it was when it was agreed to in 2015. The only difference between then and now is that Trump eventually endorsed Rubin’s take in its entirety. And because Rubin now calibrates her political compass to the opposite of whatever Trump is doing, she feels compelled to vociferously support a vapid agreement she at one time opposed on the merits.

Bias makes you stupid. It also makes pundits untrustworthy, and it’s stunning that neither Rubin nor her editors noticed her sudden reversal sufficiently to recognize that some explanation was mandatory. Maybe they think “Trump” is explanation enough.

They probably do.
