It is by now a truism that Donald Trump poses a knotty conundrum for his competitors in the Republican Party, who can attack him and his retrograde sentiments only at the cost of alienating Trump's supporters, whose votes they need to win.
Less obvious, or at least less discussed, is the parallel conundrum Trump poses for self-styled progressives. How far can they go in decrying Trump's support among white blue-collar workers without seeming to write off what was once regarded as a core progressive constituency?
It could be argued that the writing-off has already occurred. There has long been a shift in left-liberal politics away from any broad identification with "the workers" — narrowly conceived as white, male and straight — in favor of specific social and environmental issues that pose no threat to existing economic structures. In that regard, Trump's blue-collar support might be viewed as a vindication: Workers of the world, take a hike. We never liked you much anyway.
Still, there remains the vexing question of how a billionaire demagogue can win the loyalty of the very people whose class interests he opposes. What possible sense can we make of blue-collar workers of any age, gender or race supporting a man whose very existence rests on their exploitation and, increasingly, on their obsolescence? It boggles the mind, or so we like to pretend.
The usual answers — fear of terrorism, resentment of immigrants, disgust with the Washington establishment — are sound enough, but they don't go very deep. It's as if the impossibility of depth were a given.
Imperialists and vivisectionists used to argue whether their victims had souls. The argument of the 2016 presidential campaign seems to be whether white blue-collar workers do.

I talked to a friend not long ago who cited Trump's supporters as a reason for rejecting left-wing politics. "These people don't want a classless society," he said. "They want to belong to the upper class. They want to be Donald Trump."
