A Parliamentary party whose MPs are largely PR and spin merchants, whose snouts are deeper in the corruption trough than most, who favour an electoral system under which MPs are selected by party headquarters and not by local voters, who support a rigid system of central Statist control and social engineering is the very epitome of the loathsome political class. Not only that, but vote Clegg and get Von Rumpy. Voters, I suspect, know this, but right now their disgust with both Labour and Cameron's Conservatives is such that 'my enemy's enemy is my friend' in terms of using any tool to deliver a decent kicking to the Parliamentary duopoly. And really who can blame them.
Right now, the country still wants to inflict pain on politicians. This is more important that our international credit rating, than the confidence of the City, than inflation and unemployment. We still haven't seen the bastards suffer.
There is only one action that Cameron can take that will swing a significant number of voters to the Conservatives; sit down in Parliament Square, douse himself in five gallons of premium unleaded and immolate himself, in the manner of Thich Quan Duc in Saigon in 1963, with a sign simply saying 'Sorry'.
