President andrew jackson used the spoils system to
(1) attack the tariff of abominations
(2) reward supporters with united states

The correct answer is 2) Reward supporters with US government jobs.

Andrew Jackson supported this idea of the spoils system by saying that he wanted to establish a "rotation in office." He felt that constantly changing the people involved in the federal government would help ensure that there are no royal families or individuals that use their power to manipulate others.
