Conditions in Kansas Territory grew still worse. Meeting at the town of Lecompton, the proslavery convention in Kansas had drawn up a proposed state constitution authorizing slavery. The delegates represented only a minority of the people of the territory. But since they were Democrats, President Buchanan supported them. He urged Congress to accept this Lecompton Constitution and admit Kansas as a state. Of course, antislavery forces in Kansas and throughout the nation objected strongly...When a vote was finally taken on the Lecompton Constitution, the people of Kansas rejected it by a huge majority, 11,300 to 1,788. Southern Democrats and President Buchanan were furious. They blamed Douglas for this defeat.
