Still boggled by reports that Trump, having realized that the numbers on his tax plan aren’t remotely credible, has decided to fix things by bringing in as experts … Larry Kudlow and Stephen Moore. I mean, at some level this was predictable. But it still tells you a lot about both Donald the Doofus and his chosen party.

Granted that Trump is deeply ignorant about policy; still, you might have thought that he would try to signal his independence from the establishment by, say, turning to some business economist. Instead, he turned to the usual suspects from the right-wing noise machine. And what a choice!

I mean, Kudlow is to economics what William Kristol is to political strategy: if he says something, you know it’s wrong. When he ridiculed “bubbleheads” who thought overvalued real estate could bring down the economy, you should have rushed for the bomb shelters; when he proclaimed Bush a huge success, because a rising stock market is the ultimate verdict on a presidency (unless the president is a Democrat), you should have known that the Bush era would end with epochal collapse.

And then there’s Moore, who has a similarly awesome forecasting record, and adds to it an impressive lack of even minimal technical competence. Seriously: read the CJR report on his mess-up over job numbers:

The recurring “oops,” intended as a dig at Krugman, took on an unintended irony after Abouhalkah discovered that Moore’s numbers did not match those of the Bureau of Labor Statistics. In fact, Moore later acknowledged, he was using BLS numbers not from “the last five years” but from an earlier five-year period: December 2007 to December 2012. Focusing on that period is arguably dubious, because the span captures the depths of the Great Recession and the housing crash, which hit some states harder than others—and whose impact likely would have swamped any tax-rate effect. There are other issues with the quality of Moore’s argument, too, like its glancing-at-best treatment of how factors like housing costs shape population and job growth. In any case, Abouhalkah found, Moore’s numbers were wrong even for 2007-12, in ways that complicated the “low taxes = more jobs” message.

Texas did not gain 1 million jobs in the 2007-2012 period Moore measured. The correct figure was a gain of 497,400 jobs. Florida did not add hundreds of thousands of jobs in that span. It actually lost 461,500 jobs. New York, with [its] very high income tax rates, did not lose jobs during that time. It gained 75,900 jobs. Oops, indeed.

Of course, Moore remains the chief economist at Heritage. And maybe Trump believes that this is a certificate of quality, that anyone in that position must be a real expert.

Truly, Donald Trump, you know nothing.
