It's traditional for Conservative governments to fall apart amid economic catastrophe, infighting over Europe and hate-filled ranting from the racist, homophobic back benches.
And it's equally traditional for Tory prime ministers to try to paper over the cracks with a cheap and childish attack on the working men and women they despise so much.
In David Cameron's case it isn't a single failure he's trying to cover up - it's everything his unelected coalition has done since it took power.
The NHS's 65th birthday yesterday highlighted his government's carve-up and privatisation of one of the greatest achievements of the modern world.
The renewed row over Rupert Murdoch brought to mind his government's disturbingly close relationship with the media mogul's corruption-riddled empire - and Cameron's personal friendship with some of the senior figures at the centre of the phone-hacking scandal.
The ongoing scandal of US spying and persecution of whistleblower Edward Snowden reminded us how far the coalition has extended new Labour's assault on our civil liberties, despite the Lib Dems' election pledge to reverse the damage done by Tony Blair and co.
It also proved that under Cameron the "special relationship" means Britain remains Washington's enthusiastic sidekick in every crime.
Yesterday's EU referendum debate showed us again how scared Cameron is of his own backbenchers, the voting public and real democracy.
Growing dole queues, falling wages and soaring rents are a daily reminder of how his catastrophic handling of the economy has hung working people out to dry.
And that's just this week. Seven days' worth of a litany of failure, incompetence, arrogance and corruption that stretches all the way back to 2010 when Cameron's unelected coalition took power illegitimately and set about wrecking everything within reach.
No wonder he's seized on the Unite-Labour row in a desperate attempt to divert attention from his own government's disastrous showing.
Attacking the opposition is all he has left to cling to when his government has managed not one single policy it can defend.
But there's another reason Cameron has gone on the offensive so viciously and hysterically.
The People's Assembly reminded the PM of something he arrogantly allowed to slip his mind - that we will fight for everything that is ours and that the Tories are trying to take from us.
Our NHS is not lost. Health, education, the welfare state are not lost. Cameron's Tories will not get their way as long as people are willing to fight to defend the great gains we won in 1945.
The unions will be at the heart of the fight. Cameron knows that very well, which is why he is desperately trying to slander and smear them.
Labour can be at the heart of the fight too - but once this storm in a teacup has blown over Ed Miliband needs to decide which side he is on.
