After his victory in the 1904 election, President Theodore Roosevelt promised that although his first term had lasted only three years (beginning after the assassination of President William McKinley in 1901), he would adhere to the two-term precedent established by George Washington. Yet by 1912, convinced that only his progressive leadership would save the Repbulican party, Roosevelt announced his candidacy. Roosevelt contended that he had only promised to refuse a third consecutive term. Berryman shows Roosevelt attempting to dodge the anti-third term principle as he crouches before Washington's ghost. Not until 1951, after Franklin Roosevelt's four terms in office, did Congress enact the XXII Amendment to the Constitution, officially limiting Presidents to two terms.
