Both presidentialism and parliamentarism are unequivocally democratic, but each of these regimes leads to different political consequences.
The great difference is that in parliamentarism the executive branch is composed of a president or a monarch, head of state, with limited powers, and a government appointed by Parliament, which at any time can censor. In presidentialism, however, the head of state and government coincide in the same person, are not subject to parliamentary censure and the Legislative Branch is limited to the area of law making.
Therefore, in presidentialism, voters elect the head of government (who in turn is head of state); instead, in parliamentarism, the head of government is appointed by the head of state, who is voted by the people.
Manifest Destiny basically mean, "EVERYONE MOVE TO THE WEST NOW!" But with no slaves, how would they create farms to maintain themselves? Easy: expand slavery. However, this was battled against by several sources to create the Compromise of 1850. The compromise delayed the Civil War, despite politicians knowing it will eventually happen. It bought them time-- that was important! Other new states like Nebraska and Kansas were allowed to allow slavery or not. This eventually grew to where the North had no slavery and the South did, which lead to the Civil War.
