The one place where the progressives seem to have won most handily is on issues of culture. Virtually the entire entertainment, fashion, and food establishments now openly allied with the left; the culture of luxury, expressed in the page of The New York Times, has found its political voice by identifying with such issues as gay rights, transgender bathrooms , abortion and, to some extent, Black Lives Matter. In contrast, the Republicans cultural constituency has devolved to a bunch of country music crooners, open cultural reactionaries and, yes, a revolting collection of racist and misogynist “deplorables.”

Yet perhaps nowhere is the danger of Progressive Triumphalism more acute. Despite the cultural progressive embrace of the notion that more diversity is always good, the reality is that our racial divide remains stark and is arguably getting worse. As for immigration, polls say that more people want to decrease not just the undocumented but even legal immigration than increase it.

And then there’s the mountain rebellion against political correctness. Relative few Americans have much patience with such things as “micro-aggressions,” “safe spaces,” the generally anti-American tone of history instruction whose adherents are largely concentrated in the media and college campuses. Fewer still would endorse the anti-police agitation now sweeping progressive circles. For some, voting for Trump represents the opportunity to extend a “middle finger” to the ruling elites of both parties.
