There are huge areas of post-industrial decline and neglect where people are more furious than Cameron and his ilk could possibly understand, areas where any kind of antiestablishment rabble-rousing sounds like a clarion call. In depressed mountain villages and knackered seaside towns and burned-out former factory heartlands across the country, ordinary people were promised that for once, their vote would matter, that they could give the powers that be a poke in the eye. Westminster may have underestimated how very much it is hated by those to whom mainstream politics have not spoken in generations.
But honestly, when you've got over the laughing and pointing and shouting "loser" at us, what do you think is going to happen?
