27.William Howard Taft

William Howard Taft (September 15, 1857 – March 8, 1930) was the 27th President of the United States (1909–1913) and later the tenth Chief Justice of the United States (1921–1930). He is the only person to have served in both offices.
Born in 1857 in Cincinnati, Ohio, into the powerful Taft family, "Big Bill" graduated from Yale College Phi Beta Kappa in 1878[2] and from Cincinnati Law School in 1880. He worked in local nondescript legal positions until he was tapped to serve on the Ohio Supreme Court in 1887. In 1890, Taft was appointed Solicitor General of the United States and in 1891 a judge on the United States Court of Appeals for the Sixth Circuit. In 1900, President William McKinley appointed Taft Governor-General of the Philippines. In 1904, President Theodore Roosevelt appointed Taft Secretary of War with the hope that he might groom Taft, then his close political ally, into his handpicked presidential successor.
Riding a wave of popular support for fellow Republican Roosevelt, Taft won an easy victory in his 1908 bid for the presidency.[3]
In his only term, Taft's domestic agenda emphasized trust-busting, civil service reform, strengthening the Interstate Commerce Commission, improving the performance of the postal service, and passage of the Sixteenth Amendment. Abroad, Taft sought to further the economic development of underdeveloped nations in Latin America and Asia through "Dollar Diplomacy". However, Taft often alienated his own key constituencies, and was overwhelmingly defeated in his bid for a second term in the presidential election of 1912.
After leaving office, Taft spent his time in academia, arbitration, and the search for world peace through his self-founded League to Enforce Peace. In 1921, after the First World War, President Warren G. Harding appointed Taft Chief Justice of the United States. Taft served in this capacity until shortly before his death in 1930. He is the only former president to administer the oath of office to another President and the only Chief Justice to serve with associate justices whom he had appointed to the court.

29.Warren G. Harding

Warren Gamaliel Harding (November 2, 1865 – August 2, 1923) was the 29th President of the United States (1921–23). A Republican from Ohio, Harding was an influential self-made newspaper publisher. He served in the Ohio Senate (1899–1903), as the 28th Lieutenant Governor of Ohio (1903–05) and as a U.S. Senator (1915–21). He was also the first incumbent United States Senator and the first newspaper publisher to be elected President.[1][2]
His conservativism, affable manner, and "make no enemies" campaign strategy made Harding the compromise choice at the 1920 Republican National Convention. During his presidential campaign, in the aftermath of World War I, he promised a return of the nation to "normalcy". This "America first" campaign encouraged industrialization and a strong economy independent of foreign influence. Harding departed from the progressive movement that had dominated Congress since President Theodore Roosevelt. In the 1920 election, he and his running mate, Calvin Coolidge, defeated Democrat and fellow Ohioan James M. Cox, in the largest presidential popular vote landslide in American history (60.36% to 34.19%) since first recorded in 1824.[3]
President Harding rewarded friends and political contributors, referred to as the Ohio Gang, with financially powerful positions. Scandals and corruption eventually pervaded his administration; one of his own cabinet and several of his appointees were eventually tried, convicted, and sent to prison for bribery or defrauding the federal government.[4] Harding did however make some notably positive appointments to his cabinet.[5]
In foreign affairs, Harding spurned the League of Nations, and signed a separate peace treaty with Germany and Austria, formally ending World War I. He also strongly promoted world Naval disarmament at the 1921–22 Washington Naval Conference, and urged U.S. participation in a proposed International Court. Domestically, Harding signed the first child welfare program in the United States and dealt with striking workers in the mining and railroad industries. Also, the Veterans Bureau was cleaned up by Harding in March, 1923.[6] The nation's unemployment rate dropped by half during Harding's administration.[7] In August 1923, President Harding suddenly collapsed and died during a stop in California on a return trip from Alaska.[8] He was succeeded by Vice President, Calvin Coolidge.
Polls of historians and scholars have consistently ranked Harding as one of the worst Presidents. His presidency has been evaluated in terms of presidential record and accomplishments in addition to the administration scandals. The most recent Presidential rankings have had various low results for President Harding. However, in 1998, political historian Carl S. Anthony stated Harding was a "modern figure" who embraced technology and culture; sensitive to the plights of minorities, women, and labor.[9] President Harding contended with racial problems on a national level, rather than sectional, and advocated openly African American political, educational, and economic equality while in the Solid South.[10]

30.Calvin Coolidge

John Calvin Coolidge, Jr. (July 4, 1872 – January 5, 1933) was the 30th President of the United States (1923–1929). A Republican lawyer from Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of that state. His conduct during the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. Soon after, he was elected as the 29th Vice President in 1920 and succeeded to the Presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small-government conservative, and also as a man who said very little.
Coolidge restored public confidence in the White House after the scandals of his predecessor's administration, and left office with considerable popularity.[1] As a Coolidge biographer put it, "He embodied the spirit and hopes of the middle class, could interpret their longings and express their opinions. That he did represent the genius of the average is the most convincing proof of his strength."[2] Some later criticized Coolidge as part of a general criticism of laissez-faire government.[3] His reputation underwent a renaissance during the Ronald Reagan Administration,[4] but the ultimate assessment of his presidency is still divided between those who approve of his reduction of the size of government programs and those who believe the federal government should be more involved in regulating and controlling the economy.[5]
