It made racism alot worse
Popular sovereignty was an idea pushed on Douglas by Southern senators in order to pass his Kansas-Nebraska Act but Douglas made it a centerpiece of his policy because he saw it as the means to unite the Democrats, North and South, behind him. Popular sovereignty had the opposite effect: it polarized political opinion even more. Popular sovereignty in practice touched off something very close to a civil war in Kansas as pro-slavery and anti-slavery factions organized their own state constitutional conventions and led to wave of bushwhacking and political murders.
