Approaching the Election of 1848, President James Polk did not have unanimous support amongst Democrats. In fact, quite the opposite.

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 Mexican-American War well underway, the midterm elections in 1846-47 were bound to be consequential.

President James Polk, expecting a fast resolution to the Mexican-American War, “requested from Congress in August 1846 a $2 million appropriation for ‘defraying any extraordinary expenses which may be incurred in the intercourse between the United States and foreign nations.’” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 766 quoting James Polk, Diary, II, 76-77 (Aug. 10, 1846). Shortly after Congress followed this instruction and drafted a bill, David Wilmot of Pennsylvania introduced an amendment to specify that slavery would not be lawful in any territory acquired. See Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 767.

As part of the Democratic platform for the Election of 1844, the Democrats incorporated their positions on “strict construction, banking, and congressional noninterference with slavery.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 683. However, the Democrats took things one step further.

President John Tyler sought to achieve much success in foreign affairs during his presidency, and part of that success, he imagined, would be accomplished through expansion of the country. See Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 677. The annexation of the Republic of Texas to be the 28th state in the Union was to be his goal.

Justice Joseph Story wrote a decision in Prigg v. Pennsylvania that would put the United States Supreme Court in a possession of relieving northern state officials of responsibility “for returning fugitive slaves, and increasingly northern state legislatures instructed them to do so.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 654.

In 1842, John Quincy Adams presented to the House of Representatives a petition from 42 residents of Haverhill, Massachusetts, requesting that the Union be dissolved. Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 610. Henry Wise, Congressman from Virginia, “demanded the former president be censured.” Id.

While the Democrats had held up Andrew Jackson as the ideal man, the Whigs began to view Abraham Lincoln in the 1840s as the ideal man, even though his personality was “artificial—that is, self-constructed.” Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 598.

Following William Henry Harrison’s death just a month into his presidency in 1841, John Tyler rose to the presidency, in the first instance of a president dying while holding the office. See Daniel Walker Howe, What Hath God Wrought: Transformation of America, 1815-1848, 589.
