If a state was admitted as a free state, it would often result in more representation for anti-slavery advocates in Congress. This was because free states typically opposed the spread of slavery and would send representatives who supported abolitionist causes. On the other hand, if a state was admitted as a slave state, it would often result in more representation for pro-slavery advocates in Congress. This was because slave states would send representatives who supported pro-slavery policies and the interests of slaveholders.
