The change in attitude is notable. Just a few months ago, we were speculating on Trump's perceived immaturity and incompetence. By now his words and actions have removed all doubt.

Real people, academics, business and political leaders are all now unanimous in their appraisal of the President of the US. And it is so far from flattering. It's actually amazing that we can talk so blithely about it, and read and write about his failing and inadequacies without so much as a shrug. Correction, it's actually sad.

At least the uncertainty associated with the behavioural aspect of dealing with Trump has been resolved. Ironically, that gives us some clarity and stability, and is the reason for the blase response from other NAFTA leaders and negotiators.

Trump is really getting tiresome though. Many of his supporters couldn't endure his rambling and incoherent rants last night in Pheonix, and left early. I think everybody is just getting sick of him...even his dwindling fanatical base.
