Projection

And the projection ramps up, right on schedule:

"She is a totally unhinged person. She's unbalanced. And all you have to do is watch her, see her, read about her,” Trump said during a campaign rally in Windham, N.H., Saturday evening. “She will cause — if she wins, which hopefully she won't — the destruction of our country from within."

(Does the situation, objectively considered, match the words only when target and speaker are reversed? Projection.)
