I am no great fan of USA politics (to me it is all about being money rich), but great politicians are able to laugh at themselves in any nation. Those who think they are above humour deserve to fail. Sadly there are too many politicians who take themselves far too seriously both in the USA and in Europe (including the UK).
The great politicians are the gentle giants who go into power, not for self-glory, but for the greater good of the society they live in. Sadly we have very few in 21st century politics who will go down in history as great leaders.
I understand why many in the USA voted for their latest president. I also understand why so many in the UK voted to leave the EU.
