Book excerpt: Veteran political journalist Scott Farris tells the stories of legendary presidential also-rans, from Henry Clay to Stephen Douglas, from William Jennings Bryan to Thomas Dewey, and from Adlai Stevenson to Al Gore. He also includes concise profiles of every major candidate nominated for president who never reached the White House but who helped promote the success of American democracy. Farris explains how Barry Goldwater achieved the party realignment that had eluded FDR, how George McGovern paved the way for Barack Obama, and how Ross Perot changed the way all presidential candidates campaign. There is Al Smith, the first Catholic nominee for president; and Adlai Stevenson, the candidate of the "eggheads" who remains the beau ideal of a liberal statesman. And Farris explores the potential legacies of recent runners-up John Kerry and John McCain. The book also includes compact and evocative portraits of such men as John C. Fremont, the first Republican Party presidential candidate; and General Winfield Scott, whose loss helped guarantee the Union victory in the Civil War. This new edition of Almost President brings the work up-to-date with a section that explores the results and ramifications of the 2012 presidential election.
