Sure, but he doesn't need to get elected again. And there's a lesson in the fact that he spooked the living shit out of the markets and ... the sky didn't fall in, the sun still rose. He basically reversed 70 years of US trade policy overnight. If only the left were willing to act so radically.
Trump and Farage are incredibly successful politicians who have captured the popular imagination. To not take lessons from that would be idiotic. Not in terms of policy direction, obviously, but willingness to actually *do* things. And in terms of coming across like an actual human being, having a sense of humour etc.. Greens aside, the leaders of all UK parties are fucking aliens.
