Page "United States presidential election, 1844" Paragraph 1

Democratic nominee James K. Polk ran on a platform that embraced American territorial expansionism, an idea soon to be referred to as Manifest Destiny.

At their convention, the Democrats called for the annexation of Texas and asserted that the United States had a “ clear and unquestionable ” claim to “ the whole ” of Oregon.

By informally tying the Oregon boundary dispute to the more controversial Texas debate, the Democrats appealed to both Northern expansionists ( who were more adamant about the Oregon boundary ) and Southern expansionists ( who were more focused on annexing Texas as a slave state ).

Polk went on to win a narrow victory over Whig candidate Henry Clay, in part because Clay had taken a stand against expansion, although economic issues were also of great importance.

( The slogan " Fifty-four Forty or Fight !” is often incorrectly regarded as being part of this president's election campaign rhetoric ; it became a popular slogan in the months after the election, used by those proposing the most extreme solution to the Oregon boundary dispute ).
