lincoln was going to let them go do their own thing and they attacked the north. also, lincoln was a republican. the south is economically better off since slavery isn't taking everyone's jobs eve though their government tries to make it seem that way by nose diving their economy. furthermore, several states voted to ban slavery, and the confederates overrided it. they were the very definition of unconstitutional as they were fighting the government created by it. the constitution gives you rights through amendments, but it's main purpose is the organization of the government. those amendments can be removed at any time, but it's political suicide to do that.
