I have always wondered why rats that prudently abandon a ship they judge is going to sink are taken as an exemplar of disloyalty. Seems to me that any rats that stayed on board such a ship would be extremely lazy or stupid, and their extinction would improve the gene pool of Rattus rattus.
Thus the left-wing Guardian's abandonment of the Labour Party - after prudently banking the last pre-election week of income from the vast amount of government advertising that has kept it going for the last 13 years - proves nothing except its desire to survive. Its readership has nowhere else to go, and ads for jobs in the state sector are going to be as rare as hen's teeth for the next several years - so why stay on board the foundering NuLabour scow?
The Guardian's new-found enthusiasm for the Lib Dems recalls its support for the SDP when it broke away from the left-lurching Labour Party of the early 1980s. Journopukes are swift to bray in derision if politicians adapt their policies to changing circumstances; but of course when they do it, it's quite different.
It's principled, innit?
