I suppose it depends how you define elitist. If it's just about being rich, okay yeah Trump is.
But...I mean, hell, I don't even know how the *WaPo* defines "the elite". Rich people? It can't just be that. Does Trump move in "elite" circles? I don't think he ever did. If he did in the past I'd be curious what elite circle he was a part of while running for president.
