George Washington
At the end of his second term, Washington retired for personal and political reasons, fatigued and disgusted with personal attacks, and to assure a truly contested presidential election could be held. He did not feel bound to a two-term limit, but his retirement ultimately set precedent. The two-term limit to the presidency was formalized with the 1951 adoption of the Twenty-second Amendment to the United States Constitution. Washington is often credited with setting the principal of a two-term presidency, but it was Thomas Jefferson who first refused to run for a third term on political grounds.
Twenty-second Amendment to the United States Constitution
The House of Representatives took quick action, approving a proposed constitutional amendment (House Joint Resolution 27) setting a limit of two four-year terms for future presidents. Introduced by Earl C. Michener, the measure passed 285–121, with support from 47 Democrats, on February 6, 1947. Meanwhile, the Senate developed its own proposed amendment, which initially differed from the House proposal by requiring that the amendment be submitted to state ratifying conventions for ratification, rather than to the state legislatures, and by prohibiting any person who had served more than 365 days in each of two terms from further presidential service. Both these provisions were removed when the full Senate took up the bill, but a new provision was, however, added. Put forward by Robert A. Taft, it clarified procedures governing the number of times a vice president who succeeded to the presidency might be elected to the office. The amended proposal was passed 59–23, with 16 Democrats in favor, on March 12.
