By 1879, the Greenback coalition had divided, with the faction most prominent in the South and West, led by Marcus M. "Brick" Pomeroy, splitting from the main party. Pomeroy's faction, called the "Union Greenback Labor Party", was more radical and emphasized its independence, and suggested that Eastern Greenbackers were likely to "sell out the party at any time to the Democrats". Weaver remained with the rump Greenback party, often called the "National Greenback Party", and the national reputation he had earned in Congress made him one of the party's leading presidential hopefuls.
