The political and media elites are outraged beyond measure by Donald Trump’s charge that the election could be rigged. How dare he suggest such a thing, they say, for the system is as honest as the day is long!
It shows he knows he is going to lose, they say. It shows that he has no faith in the American system, and is really a fascist at heart.
In reality, it shows no such thing, but it does show that a conversation about whether this election — and the political system in general — is rigged is one that the elites most desperately do not want to have.
