President Vincent took advantage of the comparative national stability, which was being maintained by a professionalized military, to gain absolute power. A plebiscite permitted the transfer of all authority in economic matters from the legislature to the executive, but Vincent was not content with this expansion of his power. In 1935 he forced through the legislature a new constitution, which was also approved by plebiscite. The constitution praised Vincent, and it granted the executive sweeping powers to dissolve the legislature at will, to reorganize the judiciary, to appoint ten of twenty-one senators (and to recommend the remaining eleven to the lower house), and to rule by decree when the legislature was not in session. Although Vincent implemented some improvements in infrastructure and services, he brutally repressed his opposition, censored the press, and governed largely to benefit himself and a clique of merchants and corrupt military officers. Under Calixte the majority of Garde personnel had adhered to the doctrine of political nonintervention that their Marine Corps trainers had stressed. Over time, however, Vincent and Dominican dictator Rafael Leónidas Trujillo Molina sought to buy adherents among the ranks. Trujillo, determined to expand his influence over all of Hispaniola, in October 1937 ordered the indiscriminate butchery by the Dominican army of an estimated 15,000 to 20,000 Haitians on the Dominican side of the Massacre River. Some observers claim that Trujillo supported an abortive coup attempt by young Garde officers in December 1937. Vincent dismissed Calixte as commander and sent him abroad, where he eventually accepted a commission in the Dominican military as a reward for his efforts while on Trujillo's payroll. The attempted coup led Vincent to purge the officer corps of all members suspected of disloyalty, marking the end of the apolitical military. In 1941 Vincent showed every intention of standing for a third term as president, but after almost a decade of disengagement, the United States made it known that it would oppose such an extension. Vincent accommodated the Roosevelt administration and handed power over to Elie Lescot. Lescot was a mulatto who had served in numerous government posts. He was competent and forceful, and many considered him a sterling candidate for the presidency, despite his elitist background. Like the majority of previous Haitian presidents, however, he failed to live up to his potential. His tenure paralleled that of Vincent in many ways. Lescot declared himself commander in chief of the military, and power resided in a clique that ruled with the tacit support of the Garde. He repressed his opponents, censored the press, and compelled the legislature to grant him extensive powers. He handled all budget matters without legislative sanction and filled legislative vacancies without calling elections. Lescot commonly said that Haiti's declared state-of-war against the Axis powers during World War II justified his repressive actions. Haiti, however, played no role in the war except for supplying the United States with raw materials and serving as a base for a United States Coast Guard detachment. Aside from his authoritarian tendencies, Lescot had another flaw: his relationship with Trujillo. While serving as Haitian ambassador to the Dominican Republic, Lescot fell under the sway of Trujillo's influence and wealth. In fact, it was Trujillo's money that reportedly bought most of the legislative votes that brought Lescot to power. Their clandestine association persisted until 1943, when the two leaders parted ways for unknown reasons. Trujillo later made public all his correspondence with the Haitian leader. The move undermined Lescot's already dubious popular support.
