James B. Weaver (1833–1912) was a two-time candidate for US president and a congressman from Iowa. After serving in the Union Army in the Civil War, Weaver worked for the election of Republican candidates, as an advocate for farmers and laborers. He switched to the Greenback Party, and with Democratic support, won election to the House in 1878. The Greenbackers nominated Weaver for president in 1880, but he received only 3.3 percent of the popular vote. He was again elected to the House in 1884 and 1886, where he worked for expansion of the money supply and for the opening of Indian Territory to white settlement. As the Greenback Party fell apart, he helped organize a new left-wing party, the Populists, and was their nominee for president in 1892. This time he gained 8.5 percent of the popular vote and won five states. The Populists merged with the Democrats by the end of the 19th century, and Weaver went with them, promoting the candidacy of William Jennings Bryan for president in 1896, 1900, and 1908. Several of Weaver's political goals became law after his death, including the direct election of senators and a graduated income tax. (Full article...)
