This phenomenon, which started in Greece, is rampaging across the United States propelling Trump onwards and upwards and keeping Sanders in the race although he has lost the nomination but might win the presidency with more certainty than Clinton. It may be the contagion is settling here in the UK as well. This movement does not recognise party nor the verities of politics, it feeds any swing to vote against the governing establishment, the ruling order, the current state of things and whatever has gone before.

If they do the subsequent dental bill will come as quite a shock.
