Having served in both houses of the state legislature, Johnson saw election to Congress as the next step in his political career. He engaged in a number of political maneuvers to gain Democratic support, including the displacement of the Whig postmaster in Greeneville, and defeated Jonesborough lawyer John A. Aiken by 5,495 votes to 4,892. In Washington, he joined a new Democratic majority in the House of Representatives. Johnson advocated for the interests of the poor, maintained an anti-abolitionist stance, argued for only limited spending by the government and opposed protective tariffs. With Eliza remaining in Greeneville, Congressman Johnson shunned social functions in favor of study in the Library of Congress. Although a fellow Tennessee Democrat, James K. Polk, was elected president in 1844, and Johnson had campaigned for him, the two men had difficult relations, and President Polk refused some of his patronage suggestions.
