Rings are groups of bosses and are more dangerous because they are stronger. Four or five unscrupulous men working together are stronger than one working alone. So when bosses unite, they are often able to nominate whomsoever they please and to secure the election of incompetent or supine men. Rings and bosses operate largely in city and state government because the opportunity to gain control there is much greater than in national affairs. The smaller the election district, the more chance the boss has for making himself the master of it. The people as a whole cannot spend much time over politics; the boss is always at work, from one end of the year to the other. He makes friends with everybody who can help him. He is always ready to do favors. Then, when election day comes, he expects his friends to stand by him.[56] [Sidenote: Party revenue.] =How Parties are Financed.=—The work which political parties do, such as holding conventions, framing platforms, and conducting a campaign requires a great deal of money. Expenses that are necessary and quite legitimate have to be met. No organization can hold together on an empty pocketbook. So money has to be obtained, and the only way of raising it is by voluntary contributions, for the political parties have no right to tax anyone. Where does the money come from? It comes largely from members of the party who respond to the call for subscriptions sent out by their leaders. People who are well-to-do often give considerable sums although party leaders feel that it is not good policy to accept very large contributions from any one man because this may give rise to a suspicion that the subscriber hopes to get some political favor in return. The party leaders prefer to obtain the essential funds from a great multitude of small donors who prove their loyalty to the party in this way. [Sidenote: Party expenditures.] A national campaign costs each of the chief parties a large sum, several million dollars nowadays.[57] State and local campaigns cost a great deal less. The money is spent for the publication and mailing of campaign literature, for the traveling expenses of speakers, for hire of meeting-places, and for a great many other things which go to make up an election campaign.[58] The speakers and the party workers usually give their services freely, but the party must furnish the money to defray their expenses.
