Former U.S. President Jimmy Carter turned 100, marking a historic milestone as the oldest and longest-living president in U.S. history. His post-presidential legacy is celebrated for his extensive humanitarian work, particularly through the Carter Center, which has led global efforts in human rights, election integrity, and public health. Carter's bold political stances, including his criticism of Israeli policies, set him apart. His family hopes he will live until November 5 to vote for Democratic candidate Vice President Kamala Harris in the upcoming election.
