"The rows came as Mr Cameron unusually opened the conference with a scene-setting speech urging the party to make social responsibility, as opposed to Labour's state responsibility, the binding idea of liberal Conservatism. He defined his outlook in the single word of "optimism", saying: "I am optimistic about human nature. That's why I trust the people to do the right thing. Let optimism beat pessimism. Let sunshine win the day."The word 'vacuous' comes to mind. Morecambe and Wise meets Monty Python, but without the laughs. He will have to do better if he hopes to vanquish big Gordon.
Update: This underlines the point.
