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.
Manuel L. Quezon
Coincident with the local elections for the 1940, another plebiscite was held this time to ratify the proposed amendments to the Constitution regarding the restoration of the bicameral legislature, the presidential term, which was to be fixed at four years with one re-election; and the establishment of an independent Commission on Elections. With the Nacionalista Party, which had proposed said amendment in their convention, working hard under the leadership of its party president, Speaker Jose Yulo, the amendments were overwhelmingly ratified by the electorate. Speaker Yulo and Assemblyman Dominador Tan traveled to the United States to obtain President Franklin D. Roosevelt's approval, which was given on December 2, 1940. Two days later President Quezon proclaimed the amendments.
