At least Trump frightened political elites
For Republicans, the lessons are even starker. Their party, which has prided itself on free trade and family values, is so hollow at the centre that it was easily hijacked by a protectionist womanizer. And for the political establishment generally, this election should serve as a reminder of the power of populism. The elites tend to dislike populism. It is so untidy.
Donald Trump's real accomplishment is this: He has terrified the establishment. And maybe that's a good thing.
