I'd agree if there was any hope of any good faith discussion or response with him. There isn't. You're not wrong that it accomplish's nothing, but you're making that on the assumption that there exists a question you can ask him that would accomplish something. Anything he's asked in good faith, he will respond in whatever method he believes will make him look best and there's nothing you can do to get a genuine response out of him. Meanwhile, his supporters are drones who will accept any answer he gives because they are a cult who accept any answer he gives. And the ones who are on the fence aren't going to flip by seeing him perform the same circus act he's been performing for the last 4+ years.Trump fucking sucks and I genuinely believe he is bringing about the downfall of America.
But this is a shit question that accomplishes less than nothing. It actually helps Trump. It does nothing to change anyone's mind or challenge him in any real way and gives Trump fodder to advance his Media agenda. You need to call him out and press him on specific lies. Point out that two weeks ago he said he was going to have a health care plan in "two weeks" and has been saying that for 3 years. Ask whose working on it. When can we get details.
Not to mention this is grade school level "when did you stop beating your wife" shit.
So why the hell not? Any good faith interview with him is a farce, so why treat it as anything other than the joke it is.
