“I can’t really say that anything he says is true,” a Wyoming Trump supporter told us a few days ago, “but I trust him.” That mind-set explains why President Trump revved up the mendacity machine to 30 lies a day in the seven weeks leading up to the midterm elections.

More to the point, as his former press-manager-for-a-moment, Anthony Scaramucci, put it: “He’s an intentional liar. It’s very different from just being a liar liar.” Got it?

No matter. For here is where history will give us some comfort. The American Know Nothing movement peaked in the 1850s on a wave of anti-immigrant and anti-Catholic sentiment. The targets then were Irish and German.

Those dark forces morphed into the Ku Klux Klan, America’s original and most durable domestic terrorists, who waged a post-Civil War campaign of murder and intimidation. They rose again in an oddball coalition — again targeting Irish, Germans and a new element, “swarthy” immigrants from the south of Italy — that gave us Prohibition.

Intermittently dormant thereafter for nearly a century, the devil we know came roaring back when Trump launched his presidency of fear and hate. And of course, he had the full backing of the Klan elements. “Go, Trump, go,” tweeted David Duke, the former Klan leader, on this year’s election eve. Duke loved the Trump anti-Mexican ad that was so racist even Fox News pulled it.

Sadly, fear of “others” was probably the deciding factor in governor’s races in Florida and Georgia. And our petulant president on Wednesday sneered at the Republicans who refused to embrace his dark vision and lost. He didn’t mention the many who did wrap their arms around him — in the Senate races in Montana and Nevada — and were shown the door.

Kansas, always a bellwether for how race shapes this country, said, enough! Kris Kobach, one of the most anti-immigrant politicians in the country, was soundly defeated for governor there. He ran caravan ads, the full Trumpian dystopia, but it couldn’t save him.
