David Wilmot was not for slavery. In fact, he thought that all the new territories that were in development should be free from the practice.
The issue of slavery was a contentious one in the territories during the mid-19th century. The question of whether slavery should be allowed or prohibited in the territories was a central debate leading up to the Civil War. Ultimately, the issue was settled through legislation such as the Missouri Compromise and the Kansas-Nebraska Act, which aimed to address the spread of slavery into new territories.
Slavery
The Republican Party was founded just prior to the Civil War and it was a union of political supporters of: erradication slavery from the territories, internal improvements, abolition of slavery*, manufacturers, and trade intrests. *Many former Whigs and republicans (including President Lincoln) did not believe that slavery should be totally destroyed they just did not want the practice spreading to the new territories
It is the principle of Higher Law.
The Free Soil Party believed that slavery should be restricted in new territories to prevent its expansion. They advocated for free labor and opportunities for white settlers, without competition from slave labor.
The notion that people should be able to vote on the matter of slavery in the territories was called popular sovereignty. Popular sovereignty is a doctrine rooted in the belief that every human being is sovereign.
Consider this: Exactly which "people of those territories" wanted expansion of slavery. Definitely not any of the black people. Actually, nearly all the lobbying for slavery came from people living in the South who were anxious to gain more power in the House and Senate for their cause.
