The stage was set - and then Trump showed that he was a whiny baby too
'Dear Mr Trump, can I run your Twitter account for you?" That was the rather despairing cry from one conservative American blogger which became something of a running joke during the campaign. That the blogger in question was forced to issue the entreaty over the weekend, less than a fortnight after Trump won the presidency, could well be a foretaste of the four years to come.
On this occasion, the controversy was caused by the cast of 'Hamilton', the big budget Broadway musical based on the life one of America's founding fathers, Alexander Hamilton.
Using a black and Latino cast in place of the traditional white actors required for such roles, it has been described as a "cultural landmark", has cleaned up at awards ceremonies and is fully booked out for the next two years. So Mr Trump decided to pick a fight with them.
