Is Donald Trump appealing because of his policies or his ability to say “what’s on his mind”?

Noted businessman and owner of the Dallas Mavericks Mark Cuban voiced his approval of Donald Trump’s political campaign on his Cyber Dust messaging app. He explained the appeal of Trump, stating that “I don’t care what his actual positions are. I don’t care if he says the wrong thing. He says what’s on his mind. He gives honest answers rather than prepared answers. This is more important than anything any candidate has done in years.” Do you think Trump owes his popularity more to his opinions on issues or his unfiltered candor?
