Why do you deny blaming Trump? Most other republicans wouldn't have done that. He's opened up a new ability to ignore standards of behavior, but without him I really think it wouldn't have happened. And average voters have never heard of treaties like that. They voted for idiocracy realized, and they got it, but they didn't know what they voted for.
So voters are responsible (and I never convinced my dad even to this day that trump was bad, how much am I at fault), but he's an out there candidate in many ways too.
