Answer:
President James Bucchanes attempted to establish the state of Kansas as a state-accepted slave state.
Step-by-step explanation:
As president, James Buchanan (1857-1860 US President) considered that the crisis of the slave issue would disappear if he maintained a balance between the parties in his appointments, as well as persuading people to accept constitutional law as interpreted by the Supreme Court.
He was considering the legality of restricting slavery in some states, like Kansas. In his inaugural address, the president referred to the territorial issue as "a matter of little practical importance" as the Supreme Court was about to resolve it "quickly and completely".
