In the fullness of time someone will write a book on the most unlikely leaders of political parties. Till then we can but watch the Labour Party and Jeremy Corbyn engaged in a mutual love / hate relationship .... and the U.S. Republican Party as they embrace Donald Trump. There is no doubt that Trump is Nigel Farage on steroids. His views are abhorrent to many but attractive enough to some to ensure that he is a genuine contender to be the next candidate for the presidency.
If he wins the nomination he has a chance of the presidency. And then we are really in trouble as leader of the most powerful and influential country in the world is a very big deal
