Even Barbara Walters once mention she could smell him as he approached to an interview. The smell was something mentioned by several people that liked his ideas (and probably liked him too.)Smells to me like propaganda from one of his adversaries. There was a news cycle last year when the same thing was suggested about another leader, just to be annoying.
Never hear such thing is said about say Putin, doesn’t matter how much the person don’t like him. Smelling bad is not a Putin thing.
