Yep. My analysis is it's a constitutional issue. On a measure of democracy basis, parliamentary/ legislative executive systems appear to outperform presidential ones. Trump is a symptom of constitutional failure. Not its cause.
It's harder to deliver autocratic leadership via a parliamentary system. But not impossible.
At any rate, sad as it is to report, it looks like the argument which saw weakness in the US constitutional structure was valuable, as well as unpopular. It's going to be one helluva lift to remove the mess Trump leaves behind. But I would start by redoing the constitution.
