Whatever view is taken about Barack Obama’s politics, or the overall record of his presidency, it must be admitted that in terms of “family values”, Barack and Michelle Obama have been quite remarkable exemplars of domestic virtue.

Over a span of eight years, with two daughters growing through their teenage years – which can often be tempestuous – there have been no personal scandals whatsoever. No mistresses, no divorces, no misbehaviour, no wild parties, no drugs, no excessive drinking, no shady friends or companions, no dodgy financial deals: nothing. The conduct of the Obamas has been, on all personal and familial levels, impeccable.
