Opinion | The Zombie Style in American Politics

Russia didn’t help Donald Trump’s presidential campaign. O.K., it did help him, but the campaign itself wasn’t involved. O.K., the campaign had a lot of Russian contacts and knowingly received information from the Russians, but that was perfectly fine.

If you’ve been trying to follow the Republican response to revelations about what happened in 2016, you may be a bit confused. We’re not even talking about an ever-shifting party line; new excuses keep emerging, but old excuses are never abandoned. On one side, we have Rudy Giuliani saying that “there’s nothing wrong with taking information from Russians.” On the other side, we have Jared Kushner denying that Russia did anything beyond taking out “a couple of Facebook ads.”

It’s all very strange. Or, more accurately, it can seem very strange if you still think of the G.O.P. as a normal political party, one that adopts policy positions and then defends those positions in more or less good faith.

But if you have been following Republican arguments over the years, you know that the party’s response to evidence of Russian intervention in 2016 is standard operating procedure. On issue after issue, what you see are multiple levels of denial combined with a refusal ever to give up an argument no matter how completely it has been discredited.

I first encountered this style of argument a long time ago, over the issue of rising inequality. By the early 1990s it was already obvious that growth in the United States economy was becoming ever more skewed, with huge gains for a small minority at the top but lagging incomes for the middle class and the poor. This was an awkward observation for a party that, then as now, wanted to slash taxes for the rich and dismantle the social safety net. How would conservatives respond?

The answer was multilayered denial. Inequality wasn’t rising. O.K., it was rising, but that wasn’t a problem. O.K., rising inequality was unfortunate, but there was nothing that could be done about it without crippling economic growth.

You might think that the right would have to choose one of those positions, or at least that once you’d managed to refute one layer of the argument, say by showing that inequality was indeed rising, you could put that argument behind you and move on to the next one. But no: Old arguments, like the wights in “Game of Thrones,” would just keep rising up after you thought you had killed them.

And this is still going on. Even as you read about the superrich buying $240 million apartments and demanding ever-bigger mega-yachts, there’s a whole industry of people denying that inequality has gone up.

You see the same thing on climate change. Global warming is a myth — a hoax concocted by a vast conspiracy of scientists around the world. O.K., the climate is changing, but it’s a natural phenomenon that has nothing to do with human activity. O.K., man-made climate change is real, but we can’t do anything about it without destroying the economy.
