Question

T / F The newly formed Free-Soil Party, whose members were mostly
southerners, campaigned for popular sovereignty in the western
territories

Answer 1

False. The Free-Soil Party was formed primarily by anti-slavery activists and included many northern Democrats, Whigs, and abolitionists. They opposed the expansion of slavery into the western territories and were more focused on preventing the spread of slavery rather than advocating for popular sovereignty, which was the idea that the inhabitants of a territory should decide for themselves whether to allow slavery.
