Which term describes americans who were opposed to immigrants?

Nativists is the correct term to describe Americas who opposed immigration.

Explanation:

Nativism is a nationalistic fundamental ideology that says that a certain country's wealth and goods have to be distributed only or the natives. It is a protective retrograde ideology that goes against multiculturalism and diversity. It is very often fundamental in birthrights and encourages people to perform serialism and indirect discrimination. It is not only practiced in the united states and is based on the fear of being displaced by other groups of the population.

in mcculloch v. maryland (1819) the supreme court ruled that congress had implied powers under the necessary and proper clause of article i, section 8 of the constitution to create the second bank of the united states and that the state of maryland lacked the power to tax the bank.

gibbons v. ogden, (1824), was a landmark decision in which the supreme court of the united states held that the power to regulate interstate commerce, granted to congress by the commerce clause of the united states constitution, encompassed the power to regulate navigation.

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.
