Paul Krugman: Who Ate Republicans’ Brains?

"Where did this zombie horde come from?":

Who Ate Republicans’ Brains?, by Paul Krugman, NY Times: When the tweeter-in-chief castigated Senate Republicans as “total quitters” for failing to repeal the Affordable Care Act, he couldn’t have been more wrong. In fact, they showed zombie-like relentlessness in their determination to take health care away from millions of Americans, shambling forward despite devastating analyses by the Congressional Budget Office, denunciations of their plans by every major medical group, and overwhelming public disapproval.

Put it this way: Senator Lindsey Graham was entirely correct when he described the final effort at repeal as “terrible policy and horrible politics,” a “disaster” and a “fraud.” He voted for it anyway — and so did 48 of his colleagues.

So where did this zombie horde come from? Who ate Republicans’ brains? ...

The Republican health care debacle was the culmination of a process of intellectual and moral deterioration that began four decades ago...

A key moment came in the 1970s, when Irving Kristol, the godfather of neoconservatism, embraced supply-side economics — the claim, refuted by all available evidence and experience, that tax cuts pay for themselves by boosting economic growth. Writing years later, he actually boasted about valuing political expediency over intellectual integrity: “I was not certain of its economic merits but quickly saw its political possibilities.” In another essay, he cheerfully conceded to having had a “cavalier attitude toward the budget deficit,” because it was all about creating a Republican majority — so “political effectiveness was the priority, not the accounting deficiencies of government.”

The problem is that once you accept the principle that it’s O.K. to lie if it helps you win elections, it gets ever harder to limit the extent of the lying — or even to remember what it’s like to seek the truth. ...

Given this history, the Republican health care disaster was entirely predictable. You can’t expect good or even coherent policy proposals from a party that has spent decades embracing politically useful lies and denigrating expertise. ...

Now what? Maybe, just maybe, Republicans will work with Democrats to make the health system work better — after all, polls suggest that voters will, rightly, blame them for any future problems. But it wouldn’t be easy for them to face reality even if their president wasn’t a bloviating bully.

And it’s hard to imagine anything good happening on other policy fronts, either. Republicans have spent decades losing their ability to think straight, and they’re not going to get it back anytime soon.
