Take Paul Krugman in The New York Times. In Tuesday’s column he wondered how any “rational Republicans justify supporting Mr. Trump.” He concludes it’s about “feelings,” a dismissal of legitimate arguments many people, both Republicans and not, have against Hillary Clinton. But no one is more feelings-based than Krugman when it comes to Republicans. If he wants to know how people can take Donald Trump seriously, he should take a hard look at himself.

In 2012, Krugman called Mitt Romney a “charlatan,” pathologically dishonest, and untrustworthy. He said Romney doesn’t even pretend to care about poor people and wants people to die so that the rich could get richer. Romney is “completely amoral,” “a dangerous fool,” “ignorant as well as uncaring.”

In March, Krugman had a column called “Clash of Republican Con Artists.” In it, he called Trump’s foreign policy more reasonable than that of Marco Rubio or Ted Cruz and said he’s just as terrified of either of those men in the White House as he is of Trump. He wrote: “In fact, you have to wonder why, exactly, the Republican establishment is really so horrified by Mr. Trump. Yes, he’s a con man, but they all are. So why is this con job different from any other?”

Yet a few weeks ago Krugman wondered how Republicans could rally around Trump “just as if he were a normal candidate.” It was exactly Krugman who normalized him!
