Doris Kearns Goodwin weaves together the friendship, collaboration, and ultimate rupture between Theodore Roosevelt and William Howard Taft with the rise of investigative journalism that made Progressive reform possible. The dual biography traces how Roosevelt mentored Taft, championed his presidential candidacy, then grew to despise his former protégé's conservatism—culminating in their brutal 1912 contest that split the Republican Party and elected Woodrow Wilson. Goodwin, drawing on her expertise in presidential leadership, illuminates how temperament shapes political fate: Roosevelt's restless energy and need for combat versus Taft's judicial temperament and desire for consensus. Equally important are the journalists—Ida Tarbell, Lincoln Steffens, Ray Stannard Baker—whose exposés of corporate corruption and political machines created public demand for reform and gave Roosevelt his 'bully pulpit.' Goodwin recreates the world of McClure's Magazine, where talented writers conducted months-long investigations and editors shaped stories that changed laws. The book examines how Roosevelt mastered this new media landscape, cultivating reporters and timing announcements for maximum impact, while Taft's inability to manage press relations contributed to his political difficulties. Readers will encounter the birth of modern political journalism, the origins of antitrust enforcement and consumer protection, and a friendship destroyed by ambition and principle. Goodwin's narrative demonstrates how personal relationships and institutional forces intertwine to produce historical change.
