The Leave Campaign and the Trump following are part of the same phenomenon, and we continue to mock and insult it at our own peril.
In the UK, both major parties: Tory and Labour, were officially for Remain. There were elements in both parties who supported Leave and they went against party line. In England, Leave won.
In the US, neither party wants Trump in power: need I remind so many that the republican party did not take him seriously at first and have since done everything they can to keep him away from a victory.
In both cases: the political classes are so far removed from the will of the people, we are wandering blind here. This is not conservative vs left, this is people. They are angry and they are loud and they are winning.
