the two differed on various issues; Wilson opposed any federal intervention regarding women's suffrage or child labor (he viewed these as state issues), and attacked Roosevelt's tolerance of large businesses. Roosevelt won 4.1 million votes (27%), compared to Taft's 3.5 million (23%) and Wilson's gained 6.3 million (42%). Wilson scored a massive landslide in the Electoral College, with 435 electoral votes; Roosevelt won 88 electoral votes, while Taft won 8. Pennsylvania was the only eastern state won by Roosevelt; in the Midwest, he carried Michigan, Minnesota, and South Dakota; in the West, California, and Washington. Wilson's victory was the first for a Democrat since Cleveland in 1892. It was the party's best performance in the Electoral College since 1852. Roosevelt, meanwhile, garnered a higher share of the popular vote than any other third-party presidential candidate in history and won the most states of any third-party candidate after the Civil War. South American expedition (1913–1914) In 1907 a friend of Roosevelt's, John Augustine Zahm, a professor at the University of Notre Dame, invited Roosevelt to help plan a research expedition to South America. Now was the time to escape politics. To finance it, Roosevelt obtained support from the American Museum of Natural History in return for promising to bring back many new animal specimens. Roosevelt's popular book, Through the Brazilian Wilderness describes his expedition into the Brazilian jungle in 1913 as a member of the Roosevelt-Rondon Scientific Expedition, co-named after its leader, Brazilian explorer Cândido Rondon. Once in South America, a new, far more ambitious goal was added: to find the headwaters of the Rio da Duvida (Portuguese for "River of Doubt"), and trace it north to the Madeira and thence to the Amazon River. It was later renamed Roosevelt River in honor of the former president. Roosevelt's crew consisted of his son Kermit, Colonel Rondon, naturalist George Kruck Cherrie (sent by the American Museum of Natural History), Brazilian Lieutenant João Lira, team physician Dr. José Antonio Cajazeira, and 16 skilled paddlers and porters. Roosevelt also identified Leo Miller (another AMNH recommendation), Anthony Fiala, Frank Harper, and Jacob Sigg as crew members. The initial expedition started somewhat tenuously on December 9, 1913, at the height of the rainy season. The trip down the River of Doubt started on February 27, 1914. During the trip down the river, Roosevelt suffered a minor leg wound after he jumped into the river to try
