History Will Not Be Kind to Cameron, Miliband, and Clegg
Some of it's origins go back not just to the 2008 crash but in the actions of the main Party leaders between 2010 and 2015, or in Cameron's case 2016.
David Cameron decided that in order to wrest control of the Conservatives from the Euro -Skeptics (who can never be pacified), he would call for a Referendum on Europe, in an echo of Harold Wilson's move in 1975. The difference was that Wilson was actually a clever tactician, Cameron hjust thought he was. Wilson did not call one until he was fairly sure he would win, and he kept a back seat, which Cameron did not. That has ended up splitting the country and the economy facing permanent damage and the ramifications lasting decades
Ed Miliband thought that it would be good to get people from outside the Labour Party to have a say in internal elections. The result? The misery Labour has faced since 2015 and possibly leading to permanent damage for the Party and fear and anxiety elsewhere
Nick Clegg thought it would be good to get the Liberal Democrats into coalition with the Conservatives, helping to enable the events that led to the situations we are in now
Like I said, history will not be kind!
