Etheridge was elected to the
Tennessee Senate in 1869, representing the 22nd district (Weakley,
Obion and
Henry counties). He spent much of his term calling for the
repudiation of the state's debt, which was getting out of control (the state debt would be the dominant issue in state politics over the subsequent decade). He also supported a call for a constitutional convention. This convention, which took place in 1870, restored the right to vote to former Confederates, and as a result, Democrats regained control of the state government. Etheridge moved to Memphis in 1871 after his term in the state senate had ended. He endorsed
Horace Greeley for president in 1872, but declined to campaign for him as an
elector. In 1874, Etheridge ran for the state senate as a member of the People's Reform Party, or "Dark Lanterns." In October of that year, he delivered a bizarre and rambling speech at the Greenlaw Opera House in Memphis in which, according to one Memphis newspaper, he "abused everybody and everything. He abused the Democracy, Conservatism, Radicalism, funders, the press, the leaders of both parties," and "hurled his invectives and abuse at the world generally." He was easily defeated in the election by the Democratic candidate, Peyton J. Smith. Etheridge had rejoined the
Republican Party by 1876, when he endorsed
Rutherford B. Hayes for president. He ran on the Republican ticket for state senator, but was defeated by the Democratic candidate, William A. Milliken. In August 1878, the state Republican Party nominated Etheridge as its candidate for governor. His nomination was controversial, as one delegate recalled his attacks on the Republican Party in the late 1860s, and others pointed out that Etheridge's calls for repudiating the state debt ran counter to the party's platform. Etheridge subsequently declined the nomination. His replacement, Chattanooga mayor Eli Wight, was badly defeated in the general election. Etheridge became active in the
Prohibition movement in the early 1880s, and helped organize the state's Prohibition ticket in 1882. In 1884, he ran for the 9th district congressional seat on the Republican ticket, but was defeated by the Democratic candidate,
Presley T. Glass, 13,481 votes to 11,019. In 1888, Etheridge served alongside
Hugh B. Lindsay as an
at-large elector for the Republican presidential candidate,
Benjamin Harrison. In February 1891, Harrison appointed Etheridge Surveyor of Customs at Memphis. He remained in this position until he resigned in March 1894. By the early 1900s, Etheridge's health and intellect had declined. He died in Dresden on October 21, 1902 (age 83 years, 23 days). He is
interred at Mount Vernon Cemetery near
Sharon. The city of
Ethridge in
Lawrence County, Tennessee, is believed to have been named for Etheridge. ==References==
