For the record, I'd have voted "Leave" if I were British. But I've always been an Anglophile, and look forward with hope that Britain's casting off the EU yoke will lead to better trade, prosperity and good feeling between them and us. We are the central representatives of the "English Speaking Peoples", and we are everywhere and of every race, thanks to British colonization of India and South Africa and elsewhere, and the central English traditions of the common law and the rights of man.
The problem with Trump isn't that he's not raising important issues. A lot of his economic nationalism shtick (and from him, it is shtick) resonates with me, and I have no objection to the proto-Constitutional practice of tariffs (if done correctly).
The problem with Trump is Trump. He's brought the train so far, but it's time to cede the controls. He's dangerously unstable, and temperamentally the worst thing you'd want as CIC. He's baited and insulted a gigantic swath of the population. I say that's pernicious, and stupid, and the man's aggression-fueled narcissism scares the shit out of everyone I talk to.
The lesson of Brexit is to present the issue with tact and seriousness, with the support of serious, credible leaders. That's how Brexit won. The public face of the issue wasn't a ludicrous clownshow.
Trump and the issues he represents are going to lose badly to Hillary Clinton. To save those issues, and not to mention having a shot at defeating Clinton and saving the Senate, a new face is needed. Trump's got to do the right thing and respect the will of the delegates voting their consciences.
