2) Slavery was so profitable, it sprouted more millionaires per capita in the Mississippi River valley than anywhere in the nation. With cash crops of tobacco, cotton and sugar cane, America's southern states became the economic engine of the burgeoning nation. And they just didn't want to give that up.
3)Westward expansion, the 19th-century movement of settlers into the American West, began with the Louisiana Purchase and was fueled by the Gold Rush, the Oregon Trail and a belief in "manifest destiny." In the mid-19th century, the quest for control of the West led to the annexation of Texas and the Mexican–American War. ...

Southerners believed federal regulation of slavery was unconstitutional and to impose a restriction on the instituion of slavery was out of their jurisdiction.
5) The enumerated powers that are listed in the Constitution include exclusive federal powers, as well as concurrent powers that are shared with the states, and all of those powers are contrasted with the reserved powers—also called states' rights—that only the states possess.
