Started with a vengeance for the Brexit Referendum in 2016 - the possibility of gaining power was enough by a Leave campaign to start telling porkies at an industrial level.
With messaging wrapped in emotive terms, people fell for them, as they saw a return to a sepia-tinged world (which most had never lived through, & anyone that had, would never want to return to) where Britannia ruled the waves, won wars single-handedly (because wars are never far away as a reference point) & everyone else would jolly well do whatever was enforced on them.
Fast-forward to December 2019 & an election with Billy Bunter at the helm - a disorganised dollop of hair & flab, who strangely, some people aligned with because they saw him as some sort of rebel character & one they perhaps felt they shared lots of characteristics with, who simply by the use of Latin, clenched fists, three-word slogans & that strange bobbing-up & down motion he does when he gets remotely over-excited about anything, would lead us to the promised land.
The worst man at the worst possible time - was always a bullshitter.
