United States House of Representatives

In 1850, Wright was an unsuccessful candidate for election to the U.S. House of Representatives, but in 1852, was elected as a Democrat to the Thirty-third Congress. He was an unsuccessful candidate for reelection in 1854. He was again elected to the Thirty-seventh Congress to fill the vacancy caused by the death of George W. Scranton. He was elected as a Democrat to the Forty-fifth Congress and reelected as a Greenbacker to the Forty-sixth Congress. He was chairman of the United States House Committee on Manufactures during the Forty-fifth Congress.

During the Great Railroad Strike of 1877, Congressman Wright protested the use of state and federal troops to put down the strike in his District: "Troops were introduced into my district at the solicitation of the men who controlled the mines and the manufacturing establishments … There was no necessity or occasion for it … It only stirred up [the labor] element. And now, since that has been done, that element has shown its power and its strength, a power and strength that cannot be resisted, that will work its way out … You cannot suppress a volcano." (Bruce, 1959, pp. 309–10)

He was an unsuccessful candidate for reelection in 1880 and was unsuccessful in getting the Greenback nomination for President the same year, losing to James Weaver. He died in Wilkes-Barre in 1881. He is interred in Hollenback Cemetery.
