Almost certainly, in the case of Brexit, yes. An ill-considered, uninformed in many cases, decision. But a protest of sorts, yes.
After the US elected the idiot son of Bush, I realised that the voting public there are capable of infinite stupidity. Ok, he probably cheated his way to the first victory, but to elect him a second time was almost beyond belief! But then Bush was a conservative backlash against Clinton.
I fervently hope that the American public will not be so stupid as to elect Trump. I've little doubt that he's highly mentally unstable, a narcissistic egomaniac, who's capable of globe threatening stupidity and brinkmanship.
Where and why I'm concerned is because I don't think people in the UK realise just how far to the right conservative America is. Some of them make Farage look like a socialist!
