Minor parties have been attached to some special idea or interest, and they have generally expressed their positions through firm and identifiable programs and principles. Their function has not been to win or govern, but to agitate, educate, generate new ideas, and supply the dynamic element in our political life. When a third party's demands become popular enough, they are appropriated by one or both of the major parties and the third party disappears. Third parties are like bees: once they have stung, they die.
