This attack on the Coalition illustrates one of the problems with being a political obsessive. It is very hard to see anything in its wider perspective. Of course, it is true that the Prime Minister and his colleagues have made some quite serious mistakes. But these errors should be understood in the context of a serious government making its way through a mid-term squall, not as a mortal crisis. One of Mr Cameron’s very best qualities is that, though a career politician, he understands that politics matters very little to most people. In the fetid world of Westminster, that looks like weakness. In the real world, it is part of his charm and his appeal.
