What group opposed the tariff abomination?

If the question refers to the tariff acts of the early 1800's in the United States, then the answer is Southern politicians and plantation owners.

The Northern manufacturing sector of the USA wanted to curtail imported products by having tariffs on these products, giving USA companies a competitive advantage over foreign goods.

Although the South did buy Northern products, it also bought imported ones. This meant they had to pay more for imported goods. In addition, the Southerners saw the tariff acts as a means to expand Northern companies. This would increase the demand for factory workers. Many Southern common people might leave for better pay in Northern factories.
