Major scandal reached into Congress with the Crédit Mobilier of America scandal of 1872, and disgraced the White House during the Grant Administration (1869–1877). This corruption divided the Republican party into two different factions: the Stalwarts led by Roscoe Conkling and the Half-Breeds led by James G. Blaine. There was a sense that government-enabled political machines intervened in the economy and that the resulting favoritism, bribery, inefficiency, waste, and corruption were having negative consequences. Accordingly, there were widespread calls for reform, such as Civil Service Reform led by the Bourbon Democrats and Republican Mugwumps. In 1884, their support elected Democrat Grover Cleveland to the White House, and in doing so gave the Democrats their first national victory since 1856.
