I HAD MISSED THIS STORY ABOUT Stephen Moore’s new sympathy for populism:

“For God’s sake, it’s Stephen Moore!” the source said, explaining some of the lawmakers’ reactions to Moore’s statement. “He’s the guy who started Club for Growth. He’s Mr. Supply Side economics.”

“I think it’s going to take them a little time to process what does this all mean,” the source added of the lawmakers. “The vast majority of them were on the wrong side. They didn’t think this was going to happen.”

Asked about his comments to the GOP lawmakers, Moore told The Hill he was giving them a dose of reality.

“Just as Reagan converted the GOP into a conservative party, Trump has converted the GOP into a populist working-class party,” Moore said in an interview Wednesday. “In some ways this will be good for conservatives and in other ways possibly frustrating.”

Moore has spent much of his career advocating for huge tax and spending cuts and free trade. He’s been as close to a purist ideological conservative as they come, but he says the experience of traveling around Rust Belt states to support Trump has altered his politics.

“It turned me more into a populist,” he said, expressing frustration with the way some in the Beltway media dismissed the economic concerns of voters in states like Ohio, Pennsylvania and Michigan.

“Having spent the last three or four months on the campaign trail, it opens your eyes to the everyday anxieties and financial stress people are facing,” Moore added. “I’m pro-immigration and pro-trade, but we better make sure as we pursue these policies we’re not creating economic undertow in these areas.”

That’s a big shift.
