Is Nationalism still a "thing" today in the United States? Can you give me any type of
example?

Yes, nationalism has always been a "thing" in the United States, and is still today. There are several examples of this.

Explanation:

One of these examples is the promotion of economic protectionism justified by nationalist arguments. Economic measures like tariffs or import quotas, which have been implemened in the U.S. in recent years, are seen by most economists as economically harmful for the majority of people.

However, these measures still enjoy a lot of popularity not only because they do benefit sections of people, but also because of the nationalist sentiment of having a good produced within the country. This is therefore, a form of economic nationalism.

step-by-step explanation:

both are true, the congress does have the power to create banks, even if this power is not specifically described in the constitution, since there is nothing restricting it and there is power given to the congress to make "all laws which shall be necessary and proper". maryland was not allowed to tax a branch of the national bank operating there, and the supreme court decided that no state could. both of these topics were discussed in a decision of the mcculloch v. maryland case in 1819.
