The Election of 1848 was bound to be unique, as President James Polk had made clear that he would serve only one term as president. With that, the Whigs and the Democrats had to put forth candidates that could meet the parties’ respective goals of reversing President Polk’s policies (the Whigs) and expanding on President Polk’s policies (the Democrats).
One of the most outspoken Representatives in the House of Representatives, John Quincy Adams, had opposed the declaration of war on Mexico and fought President James Polk’s policies for the duration of his presidency.
With the execution of the Treaty of Guadalupe Hidalgo, the Mexican-American War had come to an end. The territory that Mexico relinquished to America held “some ninety thousand Hispanics and a considerably larger number of tribal Indians,” despite President James Polk characterizing the territory as “almost unoccupied.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 809.
