You're really missing the point on an unholy scale. Trump obviously has zero political parallels with Corbyn... but what both have in common is that they are totally off the spectrum to the status quo of politics. People are rejecting the status quo... it doesn't matter whether it's right or left... the populace is fed up with mealy-mouthed career politicians. You can keep clutching at excuses like media representation, Russian interference... but you are really missing the mood.
