How does this article reflect the strengths and weaknesses in Political Parties that can be exploited during decision making processes in Congress? What are the likely problems for the Democratic Party, and how does this situation stand to potentially benefit the Republican Party?

whose power in the senate is equal to the power of the speaker of the house?

so what is your question?

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.
