Economic expansion and the first balanced federal budget in three decades marked presidency of William Jefferson Clinton, known as Bill, who served forty-second in the United States from 1993 to 2001; the House of Representatives in 1999 impeached him on perjury and obstruction of justice charges, but the Senate acquitted him on both counts. Born William Jefferson Blythe III, he ranked as the third-youngest president, older only than Theodore Roosevelt and John Fitzgerald Kennedy. People know him the first baby-boomer president at the end of the Cold War. He is the husband of Hillary Rodham Clinton, the junior senator from New York and a Democratic candidate in the election of 2008 in the United States. People described Clinton as a New Democrat and knew him largely for the Third Way philosophy of governance that came to epitomize his two terms as president. They described his "centrist" policies on issues, such as the North American Free Trade Agreement. Clinton presided over the longest period of peacetime economic expansion in American history, which included a balanced budget and a reported federal surplus. Clinton reported a surplus of $559 billion at the end of his presidency, based on Congressional accounting rules. His presidency was also quickly challenged. On the heels of a failed attempt at health care reform with a Democratic Congress, Republicans won control of the House of Representatives for the first time in 40 years. In his second term he was impeached by the U.S. House for perjury and obstruction of justice, but was subsequently acquitted by the United States Senate and completed his term. Polls of the American electorate taken at this time showed that up to 70% were against pursuing the allegations. (New York Times December 21, 1998). Clinton left office with a 65% approval rating, the highest end-of-presidency rating of any President who came into office after World War II. Since leaving office, Clinton has been involved in public speaking and humanitarian work. He created the William J. Clinton Foundation to promote and address international causes, such as treatment and prevention of HIV/AIDS and global warming. In 2004, he released a personal autobiography, My Life.
