Trump certainly has strength and stamina. Hard to imagine how Hillary could survive the onslaught she would have to endure if Trump is her opponent.
That is my point exactly. Trump would create so much hell around Hillary forcing her to keep up that she would buckle. When Trump says that he can easily win against Hillary I think that is what he is alluding to. He would force her to constantly respond personally not through some press secretary that she would get flustered.
