The United States are a Bicameral republic, meaning that they have two legislative bodies, the House of Representatives and the Senate, each fulfilling their duties and each ensuring that legislature is adopted or not adopted.
Republicans, farmers and other debtors is the right answer.

The tariffs also generated other countries to counter by placing taxes of their own on the farm products of the United States. This resulted in the loose of share in the overseas market for the farmers.
