The 1912 presidential election was the peak of progressivism in the United States. Presidential candidates Taft, T. Roosevelt, and Wilson each had reform agendas going into the election. Despite the political parties; republican, democrat, or bull moose the political spectrum was filled with progressive platforms.
Teddy Roosevelt's presidency was responsible for a series of reforms concerning the enviornment. The Newlands Act (1902) created the National Forest Service, the Antiquities Act (1906) protected places such as the Grand Canyon from industrial development. In addition, the Pure Food and Drug Act (1906) regulated food preparation and medicines. Lastly, Roosevelt's 'trustbusting' efforts led to a series of Supreme Court decisions prohibiting monopolistic practices.
Howard Taft continued to follow Roosevelt's agenda leading to even more Supreme Court decisions dismantling the powerful trusts. In 1911 J.P. Morgan's railroad monopolies were ordered to break apart while J.D. Rockefeller's Standard Oil monopoly was dismantled.
Woodrow Wilson campaigned to completely dismantle the corporate trusts by advocating for the Clayton Anti-Trust Act. He also pushed for the passage of a graduated income tax, the ratification of the 16th Amendment, and the creation of the Federal Reserve.
