I think part of the problem with Trump's rambling is that it's never really even specific, or coherent, enough to be considered factual or otherwise. Usually he's just riffing on something he heard someone else say on a talk show or something. It's like listening to a blowhard ranting at the town diner. Half of it's bullshit, but no one really cares. They either agree with the general sentiment, or don't. The facts are irrelevant.
