Trump is only a madman to those that disagree with him because he's Trump.
I disagree with his stances on Climate Change and Grabbing Genitals, but I agree with him on some points too, like withdrawal from TPP, screening muslim immigrants, and trolling the press. (Honestly, it's a lot of fun to see the press get their panties in a twist.)
He's currently polling at a 59% job approval rate, BTW. So...not everyone agrees with your diagnosis of him being a "madman."
