It is surprising how little attention is given to the idea of expansion in general, and the war with Mexico specifically, in the platforms of American political parties between 1832 and 1848. With Texas, Oregon, Manifest Destiny, and the Mexican War defining the period, I expected to find these subjects being addressed in the party platforms. It is only after the fact, the Mexican- American War that the parties mention the new territories. More prominent are statements concerning constitutional questions: limited government versus large scale internal improvements, and slavery. They generally feature praises of the various candidates. Below are planks that address expansion and the war with Mexico. One plank, the #6 plank in the 1848 Whig platform, is over-board in its description of Taylor’s virtues.
