Thiệu saw an opportunity to consolidate his personal power and he took it. His only real political rival was Vice President Kỳ, the former Air Force commander, who had been outmaneuvered by Thiệu in the presidential election of 1967. In the aftermath of Tet, Kỳ supporters in the military and the administration were quickly removed from power, arrested, or exiled. A crack-down on the South Vietnamese press also ensued and there was a worrisome return of former President Ngô Đình Diệm's Cần Lao Party members to high positions in the government and military. By the summer of 1968, the President had earned a less exalted sobriquet among the South Vietnamese population, who had begun to call him "the little dictator."
