It is difficult to imagine, from the perspective of an affluent, trust-funded family, why you would want to remain an MP after your paws have been removed from the throat of the nation. The news that there will be a by-election in David Cameron's constituency is hardly surprising given the inconsistent and mendacious positions he adopted throughout the referendum campaign, nor in the fragility of the roots of his purported compassionate Conservatism.
As a Prime Minister, he has been a monumental disaster. In terms of making catastrophic misjudgements afflicting the wider citizenry, he is up there with Neville Chamberlain, combining it with the flair of Douglas Home and the slimy insincerity of Tony Blair and Harold Wilson. Playing the purported reasonableness card enabled him to make advances in 2010, while riding the far right insurgency that, as with the much more creditable John Major, proved to be his ultimate downfall.
Whereas Major faced down his opponents within his own party, Cameron's position was too weak to address the dribbling backwoods lunatics and the neoliberal ideologues. Instead he propitiated, simpered and preened himself, never able to take a decision that was focused purely on the national interest or even betraying any hint of either values or a strategy. Everything was expedient, from the co-option of the Liberal Democrats as human shields to the determination of a complex and irrevocable long-term decision through a referendum which was improperly drafted, without legal clarity, and whose ramifications, whatever the final outcome, will paralyse and emasculate the political and economic climate for two decades. Hardly the actions of a statesman.
In bequeathing this legacy to the country, he is lucky to be able to run away. The rest of us are not, or at least not until the forces of idiocy are vanquished. In the meantime there will be unrest, there will be decline and depression, and there may be the final collapse of what passed for a United Kingdom. All down to his legacy and vanity. All that is left is to look forward to the by-election.
