In the hundreds of TV, newspaper and magazine interviews Donald Trump has done over decades of his career, certain themes he talked about remained constant. That tells me he is principled and consistent.
That's my point of view after reading many of his statements and seeing and hearing many of his interviews. Those of you who dislike Donald Trump will of course disagree. But, before dismissing it, take a look at his public statements the last 35 years. He's saying the same things today.
