I have always said that Corbyn spouts a lot of claptrap because he is wedded to politically correct Labour dogma which is anti common sense. I prefer Trump and Farage to Corbyn because of common sense. But that doesn't mean I don't like Corbyn, he just has less common ense than Farage and Trump.
UKIP grew because Conservatives had had enough of Cameron and the Oxbridge hoody huggers. They couldn't vote for Corbyn because he is politically correct, and ordinary working class Labour voters are also not politically correct, so as Conservative voters raised UKIP in the polls, Labour voters joined them.
But the Oxbridge teams will end UKIP because it is a populist movement. Labour is more powerful. Farage, who is UKIP, has stood down, so UKIP's appeal will now plummet, because although Diane James is excellent, she hasn't got Farage's appeal and his ability to take it to the metropoliatn elite.
So UKIP will string along and many of us will keep voting for them to annoy the metropolitan elite, but they can't win.
The really exciting change in politics in the country is Corbyn. If he is able to articulate a populist policy and overturn the metropolitan elite consensus then he will win and even some conservatives and many UKIP voters will vote for him despite of his political correctness.
