Donald Trump Is Saving Our Democracy -- NYMag

In the short time since Trump declared his candidacy, he has performed a public service by exposing, however crudely and at times inadvertently, the posturings of both the Republicans and the Democrats and the foolishness and obsolescence of much of the political culture they share. He is, as many say, making a mockery of the entire political process with his bull-in-a-china-shop antics. But the mockery in this case may be overdue, highly warranted, and ultimately a spur to reform rather than the crime against civic order that has scandalized those who see him, in the words of the former George W. Bush speechwriter Michael Gerson, as "dangerous to democracy."
