The presidency
Buchanan supported the Supreme Court’s Dred Scott decision and backed the proslavery Lecompton constitution for Kansas, alienating many northern Democrats. After Lincoln’s election, southern states began leaving the Union. Buchanan argued that secession was illegal but denied that the federal government had clear power to coerce a state back into the Union. His response left the crisis unresolved for his successor.
