When Theodore Roosevelt entered national politics as the Republicans' nominee for the vice presidency in 1900, he was only forty-one years old. However, he had caught the public's attention with the popular version of his life story. Child of East Coast privilege. Sickly, bespectacled youth. Naturalist and author. Harvard graduate. New York assemblyman. Young widower. Badlands cowboy. Civil Service reformer. Urban police commissioner. Assistant Secretary of the Navy. Rough Rider and war hero. Enemy of political bosses as governor of the nation's most important state. Attentive husband to his second wife, Edith, and the father of six children. Few candidates for the presidency or vice presidency have enjoyed the elevated level of admiration accorded Roosevelt in the waning days of the nineteenth century. His nomination for the vice presidency was Roosevelt's debut as a candidate for national office. American Cyclone presents the story of his campaign, a whirlwind effort highlighted by an astounding whistle-stop tour of 480 communities across twenty-three states. Eighteen of those states gave a plurality of votes to the McKinley-Roosevelt ticket, a gain of five states for the Republicans over 1896. Everywhere Roosevelt went, admiring throngs and dramatic events helped forge him into the man who would soon be the twenty-sixth president of the United States.
