The term '20/20 vision' implies good if not perfect sight. May the advent of 2020 - a new year, a new decade - see a lifting of the fog which has recently blurred the edges of what can be described as 'acceptable political discourse', and in the process refocus voter attention on the clear need to demand from elected representatives, a display of basic decency and decorum in public life - both of which have been seriously lacking in the behaviour of some high profile politicians on both sides of the pond, on an eye-watering number of occasions. That indeed would be a sight for sore eyes.
