The correct answer to this open question is the following.
The collapse of the Second Party System made a political compromise between the North and South less likely because the parliamentary was the viable option to negotiate differences between the northern and southern states. With the collapse of the Second Party System comprised of rivals Democratic Party and Whig Party, differences and animosity increased between abolitionists in the North and pro-slavery in the South. The so-called party's crisis of 1850 opened the door to what was imminent, a military conflict between the Union and the seceded states that formed the Confederation.
