1904 to 1944. Four decades that were crucial for the United States. Then, unlike today, presidential nominating conventions mattered. Their outcomes altered history. Without the twists, turns, and dealmaking at conventions, there would have been no President Woodrow Wilson, no rejection of a third term for President Theodore Roosevelt, no President Warren Harding, no Vice President Calvin Coolidge, and no Vice President Harry Truman. How did the victors at conventions prevail, and why were the losers defeated? This book tells those intriguing stories.
