They don't have to watch the show to know whether they agree or disagree with Trump's position.
How can anyone agree or disagree without seeing it? Or are you just trying to insinuate that Trump supporters blindly believe everything he says without question? If that's it, you're very wrong. Most of them support him because they believe he's simply far better for our country than Clinton. That's the only reason I even entertained the idea. But in the end only *I* represent my views, so that's how I voted.
