After the hopeful Wisconsin flutter, might this be the beginning of an Egyptian summer in New York? Spring has absconded from the heart of political America for far too long. The frozen winters of the Reagan and Bush years didn't melt with Clinton or Obama: hollow men who rule over a hollow system where money overpowers all and the much-maligned state is used mainly to preserve the financial status quo and fund the wars of the 21st century. Discussion, serious debate, openness have virtually disappeared from mainstream political life in the United States and its more extreme versions in Europe, with Britain as the cock on the dung heap. The extreme right is small. The extreme left barely exists. It is the extreme centre that dominates political and financial life.
