Note 52 — Chapter VIII · POLITICAL PARTIES AND PRACTICAL POLITICS

There have been some critical issues at different times in American history, such as nullification, slavery, secession, reconstruction, green-backs, free silver, the regulation of trusts, imperialism, the league of nations, and so on. Most of the leading issues in recent years have been economic in character; they have been concerned with such matters as the railroads, the merchant marine, the regulation of industry, immigration, relations with Mexico, banking reorganization, the extension of aid to agriculture, conservation, budget methods, and international trade.
