But in this view, Mr. Trump is not so much a movement leader as he is a vessel. “We see a lot of potential here with this particular administration,” Mr. Boychuk said, “but we’re not going to live or die by him.”

If nothing else, these conservatives see Mr. Trump as a disrupter who is already jolting a movement they believe is badly ossified and reflexively devoted to an agenda of corporate tax cuts, global trade agreements and military adventurism — “checklist conservatism,” as an essay by Chris Buskirk, the publisher of American Greatness, described it.

They accept the almost socialist-sounding “pro-worker” label. They believe the Republican Party has been far too complicit in the expansion of the federal bureaucracy, what they scorn as the “administrative state.” And they tend to de-emphasize social issues as a priority.
