It suddenly occurred to me that I need to stop dressing like a radical lesbian bag lady if I am going to ingratiate myself with the voters in the constituency in which I am, perhaps unwisely, standing for the SDP. ‘Always look better than them’ is the injunction made by Steve Martin in the underrated film Leap of Faith: he plays a charlatan evangelistic preacher, which is not a million miles away from standing for parliament, although probably rather more fun.
