In a campaign that became infamous as one of the dirtiest in history, Cleveland, aided by the Mugwups led by Carl Schurz, defeated Blaine by a narrow margin.Much of Cleveland's presidency was dominated by debate over the protective tariff. In 1888, after Blaine declined to run, the Republicans chose Benjamin HARRISON of Indiana as their nominee. Campaigning strongly in favor of the protective tariff, Harrison defeated Cleveland by an electoral vote of 233 to 168, although he received 100,000 fewer popular votes.

McKinley received support from the industrial Northeast and the business community. Bryan receiv...
