Parties are instruments of government. They are the vehicle by which the people achieve their aims. What good are elections, if the party they elect disintegrates when the time comes to fulfill campaign promises? What does it matter to vote for one man rather than another, one set of principles over another—if struggles for personal advantages and factional victory prevent those principles and promises from being carried into effect? The business of parties is not just to win elections. It is to govern. And a party cannot govern if it is disunited.
