Long-term thinking? "Progressive politics"? "Implementing systemic reform"? "Fighting the excessive power of capitalism and putting that power back where it rightly belongs, in the hands of the people"? Fair play to Charlotte Church for getting involved (I genuinely mean that), but, much as I agree with her general sentiments, I can't help thinking that backing Labour in the hope that they morph into the Green Party when in power is somewhat bizarre.
