Answer:
Democrats
Explanation:
An example of someone who argued in favor of states rights includes John C Calhoun(former vice president of the U.S) who contributed by writing the theory or doctrine of nullification. This proposed that states inhabited within the union should have the natural right, and are not subject to unconstitutional laws made by the federal government.
Therefore, democrats were in favor of states rights, and did not appreciate social, and economic involvement of the federal government. While the Whigs favored this strong federal government through the power of congress.
John C Calhoun was a democrat.
