Labour's left/right issues are simply an underdamped pendulum swing. The party definitely did go right of the established centre under Blair. Eventually it got pulled back, but too far as an overreaction. It'll swing less left eventually and hopefully get to it's true home, left of centre position again. But it needs to learn that it's there representing the will of the people, not trying to control normal citizens, telling them what they should choose, or trying to make them carry papers to justify themselves to the authorities.
