In past elections, when there sometimes really was not much political difference between Democrats and Republicans, this made a certain sense. Broadly speaking, on economics and foreign policy, the candidates often would be in accord, with Republicans more inclined to favor the interests of big business and Democrats defending the interests of labor.
在过去的大选中——那时民主党和共和党的政治分歧还没有那么大——这有点用。大体而言，在经济和外交政策方面，候选人通常按常规出牌，共和党更支持大企业的利益，而民主党是劳工利益的捍卫者。因此，选民不会抱怨难以决定自己的选票。既然他们无法做出理性选择，那么不妨跟着感觉走，把票投给看起来最面善的就是了。
