If western territories became slave states, the balance of power in the Senate would shift in favor of pro-slavery interests. This is because each new state admitted to the Union would receive two Senate seats, potentially increasing the number of slave states relative to free states. This shift could lead to heightened tensions over slavery-related legislation and influence national policies, potentially exacerbating sectional conflicts leading up to the Civil War. Ultimately, it would solidify the political power of slaveholding states in the federal government.
