"Telling it like it is" isn't actually, you know, telling it like it is. It is this feeling - a brunt, disregard for feelings of the people you oppose because the thing you are saying is so obviously needed even if it hurts some people, we have to say it. Whether we actually need to or not is irrelevant - especially in TRUMP's case where a large part of what he says is not true or even ridiculous. He gives you that emotion.
Say what you will, Trump's ability to speak his mind is one of the things his supporters like about him. For Clinton to take a position on anything, she has to figure out what plays well with people and how to best spin things. Trump will tell you what he thinks. Sure, you can disagree with him or dislike his style, but you can't say he's not willing to answer a question that's put to him or give voice to an unpopular position.
