It is understandable that politicians should talk up their own vision of the future and talk down what others have to say. All of this is most credible if it does not go too far, and if it bears some resemblance to what the same politicians have achieved when they have been in power.
我们可以理解政治家渲染自己的未来目标，而对别人的目标进行淡化处理。但做得不太过火才相对可信，并且此人在过去掌权时也应该取得过某些相似的业绩。选民们往往在一英里外就能辩认出政界匹诺曹和说谎者的长鼻子。但他们也并不用圣人的标准来要求自己的当选代表。他们愿意在一定程度上适用无罪推定（目前为止这是政界领袖能够拥有的最重要的品质）。我猜想在投票当天，戴维·卡梅伦首相在露面时会表现出这种特点。
