Last month saw two countries change their leader: the United States of America and the Gambia (which is second country beside the Bahamas to have ‘the’ before it). While there may be some discomfort when power changes hand, especially with opposition succeeding the incumbent, the difference could not have been more starker when comparing the two countries.
There was the issue of how Trump thought the transition was not smooth (see his Tweets).
Was it just down to the practice of democracy? May be because Obama talked about winning against Trump if given the chance (with Trump retorting swiftly).
