SOMETIMES in politics, not being someone else is more important than being yourself. The most glaring example of this can be seen across the Atlantic, where President Joe Biden is on course to slip seamlessly into the history books as a forgettable President. There have been many before him – men who have been there, sailed the ship without hitting any large rocks but, ultimately, done nothing terribly memorable. President Biden’s job is not to be President Biden – it is to not be President Trump. That is the essential requirement of the post, and he will most likely perform it perfectly competently for four years while he keeps his chair in the Oval Office warm for his successor, presumably Vice President Kamala Harris.
