In America last week I sought to work out who hates Donald Trump more: Democrats or Republicans. The answer, I soon realised, was Republicans; his own party is in a seething panic about what appears to be the probability of his becoming their presidential candidate.

A group of them, whose spokesman is a failed presidential candidate from the last two elections, Mitt Romney, are trying to rally support and raise money to stop him. The problem is that they don’t have a plan, and they fail to see what their party is now really like. They also fail to see what an unhappy, troubled, angry country America now is, and how Americans feel their mainstream politicians have not responded to their fears.

By March 15 there will have been eight more Republican primaries, and Trump leads in the polls in almost all of them – including Florida, where he is 20 points ahead of Marco Rubio, whose home state it is. In 10 days, any doubt about Mr Trump’s candidacy could well be eliminated, as he stays on course to secure the 1,237 delegates he needs to be nominated.
