You hear "populism" all the time, but that's the wrong label for President Trump's vague ideology. A better one: America-first, Trump-style nationalism.

When you parse his Inaugural address — and watch the unmistakable prominence and power of deeper-thinking nationalists like chief strategist Steve Bannon, policy guru Stephen Miller and Attorney General-in-waiting Jeff Sessions — you see a Trump form of nationalism emerging.

Its origin: Trump has bounced all over the place on most issues. But he has been a fairly consistent critic of trade deals, outsourcing and China. Starting several years back, Bannon, Miller and others searched for a vessel for their more fully formed version of nationalism, just as a similar wave swept across Europe. Trump embraced the notion, if not the specifics, and the inauguration speech was the advisers' victory lap. It was also Trump's fullest public embrace of it.
