Roosevelt had made a name for himself in years after the Second Mexican War. His position as a war hero and a Democrat virtually guaranteed his election. Nonetheless, he faced a comparatively formidable opponent in SocialistEugene V. Debs. Debs was the first Socialist to be elected to the United States Congress, and so had a level of recognition and public appeal that his predecessors lacked. Nonetheless, Debs' notions of economic equality just didn't resonate with the voters the way the concrete goals of Remembrance did.
Roosevelt handily defeated Debs, continuing the Democratic monopoly on power. Within two years, the country was at war with the Confederacy and Canada, a war which Roosevelt eagerly and vigorously pursued, a war which the U.S. ultimately won under Roosevelt's leadership.
Roosevelt and Debs faced-off again in 1916, with the same result.
