Panama Canal Zone
The Panama Canal Zone () was an unincorporated territory of the United States from 1903 to 1979, centered on the Panama Canal and surrounded by the Republic of Panama. The zone consisted of the canal and an area generally extending on each side of the centerline, excluding Panama City and Colón, which otherwise would have been partly within the limits of the Zone. Its border spanned three of Panama's provinces. When reservoirs were created to assure a steady supply of water for the locks, those lakes were included within the Zone.
Dan Smoot
A subsequent 1964 issue opposed a proposal by U.S. President Lyndon B. Johnson to transfer sovereignty of the Panama Canal to the Republic of Panama. Johnson failed in his attempt, but President Jimmy Carter in 1978, with bipartisan U. S. Senate support led by Moderate Republican Howard Baker of Tennessee, prevailed by a one-vote margin to extend control of the Canal Zone to Panama. It was Moderate Republican support for many Democratic proposals that particularly angered Smoot, who gave up on the national Republican Party as a viable alternative to the majority Democrats of his day.
