Congress

In 1888, he ran as a Labor Party candidate against Democrat William H. Cate for the Fifty-first Congress; although Cate was initially declared re-elected, Featherstone challenged on the grounds of election fraud. Following the Featherstone v. Cate hearings held in the U.S. House of Representatives, Featherstone was seated in Congress in 1890 and served until March 3, 1891.^[2] He was an unsuccessful candidate on the Union Labor ticket for reelection in 1890 to the Fifty-second Congress.

By 1892, constantly under attack for supporting efforts to preserve the right of blacks and poor whites to vote, Featherstone was one of the Union Labor members who joined the Populist Party, and served as platform committee chairman at the state party convention, which adopted a resolution (introduced by a black delegate from the St. Francis County delegation) calling on Arkansas "to elevate the down-trodden sons and daughters of industry in all matters ... irrespective of race or color." Featherstone was the head of the Arkansas delegation to the Populist national convention in Omaha. After the defeat in 1892 of the Arkansas Populists, Featherstone abandoned politics as populism faded, and Arkansas Democrats reasserted their political dominance by means of laws that disenfranchised many black and poor white voters.

Featherstone eventually moved to Galveston, Texas, where he engaged in railroad building and in development of the iron resources of Texas. During the Spanish–American War in 1898, he was commissioned as a first lieutenant, and became captain, in the First United States Volunteer Infantry, a unit mustered out in Galveston that saw no service outside the United States.^[3]
