The Kansas-Nebraska Act of 1854 was meant to slave the nation from sectional conflict over slavery. The Kansas-Nebraska Act of 1854 did opened up much of the western United States to slavery. However, would have most of the territories entered the union as slave states? Would have Bleeding Kansas became Bleeding Colorado, Bleeding Idaho, Bleeding Montana etc.? Did the South have the political power to fight for slavery in all of the twelve future states the Kansas-Nebraska Act of 1854 opened up to slavery? I can not see why Southern states would not have tried to turn all the incoming states in to slave states and Northern state try to turn all these incoming states into free states. So would have there been bloody fighting over every incoming state? If all twelve of these new states plus Arizona and New Mexico, would have adopted slavery could the Civil War could have been avoided. The slave states could have dominated the US government for the next 100 to 150 years but would have the Northern States at some point have seceded?
