Gould argues that Taft wanted to be president and had an ambitious agenda when he took power in March 1909. Approaching his duties more as a judge than as a charismatic executive in the mold of Theodore Roosevelt, Taft soon found himself out of step with public opinion. Gould shows how the Payne-Aldrich Tariff and the Ballinger-Pinchot controversy squandered Taft's political capital and prepared the ground for Democratic victories in the elections of 1910 and 1912. His seamless narrative provides innovative treatments of these crucial episodes to make Taft's presidency more understandable than in any previous account. On Canadian reciprocity, dollar diplomacy, and international arbitration, Gould's work goes beyond earlier cliches about Taft's administration to link his tenure to the evolution of the modern presidency. The break with Theodore Roosevelt in 1912 doomed the Taft presidency, and Gould supplies an evenhanded analysis of the erosion of their once warm friendship. At bottom, the two men clashed about the nature of presidential power, and Gould traces with insight how this personal and ideological rupture influenced the future of the Republican party, and the course of American politics.
