Jeremy Corbyn won the leadership of the UK Labour Party. As usually happens when the left scores an electoral victory, the center-left and others has made sure to inform Corbyn and his supporters that it is bad that he won and that he never should have tried to win. I am more familiar with this in the American context where every left-wing electoral effort is similarly cast as irresponsible. Given these attitudes, I am left to wonder what exactly people think the left is supposed to do electorally?
