For many years after the missouri compromise, political parties:

Avoided the issue of slavery.

Explanation:

When Missouri requested admission to the Union as a slave state in 1819, this change represented a threat to the balance of power between slave and free states. The Missouri Compromise was then developed as an effort by Congress to defuse the conflict. This was a piece of legislation that allowed Missouri to join as a slave state with Maine admitted as a free state at the same time in order to maintain the balance in the Senate. Moreover, it prohibited slavery north of the 36°30′ parallel, excluding Missouri. After this compromise, political parties avoided the issue of slavery for years.

demand is the need and oportunity to buy a given good or service.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
