What kind of laws do the supreme court deal with?

The Supreme Court functions as a last resort tribunal. Its rulings cannot be appealed. It also decides on cases dealing with the interpretation of the constitution (for example, it can overturn a law passed by Congress if it deems it unconstitutional).

Explanation:

abraham lincoln, according to anyone who was connected with agriculture, represented the worst of northern politicians. shortly after lincoln was elected, south carolina seceded from the union. they along with other southern states, retained their anger. in a way, it was their own fault: the democrats were split in the south. some wanted slavery to be extended in other states that were about to join the union and some didn't want it badly enough. lincoln had a solid backing from his party: the republicans were united in not wanting slavery to be expanded.
