Trump said this after Hillary Clinton accused him of being a New York Racist Bigot:

Trump slammed Hillary by saying, ‘You’re racist, you’re racist, you’re racist,’ they keep saying it, ‘you’re racist.’ It’s a tired, disgusting argument, and it’s so totally predictable. They’re failing so badly. It’s the last refuge of the discredited Democrat politician. They keep going back to the same well, but you know what? The people are becoming very smart. They’ve heard it too many times before. The well is dry.” Politico
