Two years ago this week, the nation’s unemployment dipped below 8% for the first time since the start of the Great Recession. Almost immediately, Republicans were outraged – the good news couldn’t be real, they said, but rather must be the result of an elaborate conspiracy.

Friday we learned that the nation’s jobless rate has dipped even lower, dropping below 6% for the first time in over six years. Rush Limbaugh told his audience that the 2012 data was “entirely made up” and “artificially manufactured,” and the 2014 data is worse.

“[T]his today is just as illegitimate. This 5.9% number is even more illegitimate than the 7.9% number. There’s no way that this country has an economy producing jobs with an unemployment rate of 5.9%. It just isn’t happening…. [I]t isn’t real.”

Over the course of two years, from Jack Welch to Rush Limbaugh, we just haven’t seen much in the way of progress on the scourge of denialism among President Obama’s critics.

I’m reminded of this piece from Alex Seitz-Wald, now an msnbc colleague, written when Fox News first began pushing these conspiracy theories in earnest: “If it weren’t improper to psychologically analyze strangers, one might think the Fox hosts are displaying a textbook example of cogitative dissonance here, a psychological phenomena in which people who hold on strong belief about something invent (sometimes farfetched) explanations for new evidence that conflicts with their existing views. Obama is bad for the economy, the jobs numbers show the economy is doing better, so there must be something wrong with the jobs numbers.”

If nothing else, Limbaugh’s assessment was helpful in its candor: in his mind, there’s just “no way” that reality is real. It can’t be real, therefore, it’s not real, evidence be damned.

I can appreciate where the denial comes from. Republicans just know that last year’s tax increases on the wealthy are slowing the economy; they just know that “Obamacare” is destroying the job market; they just know federal regulations are strangling economic vitality.

And when reality presents proof that they’re mistaken, well, reality must be wrong, too. “Those Chicago guys” must be at it again.

The right was so certain the Affordable Care Act would fail that it literally couldn’t believe the enrollment numbers. The right was equally certain that Mitt Romney was cruising towards a landslide victory, so it seemed obvious to them that pollsters conspired to ensure that survey results were “skewed.”

Climate data is politically inconvenient, so it must be rejected. The job numbers are politically inconvenient, so they must be ignored, too.
