President Kirchner took office on May 25, 2003. He reshuffled the leadership of the Armed Forces, overturned controversial amnesty laws that protected members of the 1976-1983 dictatorship from prosecution, and kept Lavagna on as economy minister for most of his presidency. Kirchner's administration saw a strong economic rebound, and foreign debt reestructuring. The 2007 general election took place in ten provinces in September and Kirchner's Front for Victory won in six provinces. Hermes Binner was elected governor of Santa Fe, becoming the first Socialist governor in Argentina's history and the first non-Justicialist to rule the rather wealthy Santa Fe province, and Center-left Fabiana Ríos (ARI) became the first woman to be elected governor of Tierra del Fuego, while the right-wing Mauricio Macri was elected Chief of Government of Buenos Aires City in June 2007. On December 10, 2007, Cristina Fernández de Kirchner took over the presidency from her husband, after winning elections with 44% of the vote. Néstor Kirchner remained a highly influential politician during the term of Cristina Fernández de Kirchner. The press developed the term "presidential marriage" to make reference to both of them at once. Some political analysts compared this type of government with a diarchy. After proposing a new taxation system for agricultural exports, the Cristina Fernández's Government had to face a severe lock out of the sector. The protest, which spread over 129 days, was quickly politicized and marked a inflection point in her administration. The system was finally rejected in the Senate by the opposite vote of the Vice president Julio Cobos. The political style of the government changed with the Death and state funeral of Néstor Kirchner. Cristina slowly distanced from the traditional structure of the Justicialist Party and favored instead The Campora, a group of young supporters led by her son Máximo Kirchner.
