There are two pieces to this episode. First, a tour of what Donald Trump has done — and what he has backed down from doing — over the last few days. There’s a lesson there. Perhaps Democrats are starting to learn it. Then I wanted to hear the view of Trump’s first weeks back in office from someone on the right — someone who agrees with many of Trump’s policies, but also understands how the government works and who cares about our Constitution. Yuval Levin is the director of social, cultural and constitutional studies at the American Enterprise Institute. His latest book is “American Covenant: How the Constitution Unified Our Nation — and Could Again.” What struck me about our conversation is that, on the one hand, Levin is less alarmed about much of what’s happening than I am. But on the other hand, he’s a lot less impressed by what Trump is actually getting done — and how these moves are likely to work out for him — than most Democrats I know. It’s a perspective very much worth hearing.
