Example Input: Passage: Political families started becoming more apparent in the national political scene after World War II and gradually turned into hereditary politics, especially in the provinces. In 1946, Vicente Sotto became a senator after his brother Filemon Sotto previously held a position in the Senate before the war. The 60s saw more frequent instances of relatives getting elected in the Senate such as the election of the brother of then President Ramon Magsaysay; of Magnolia Antonino as Senator after her husband Senator Gaudencio died; of Sergio Osmeña Jr. who was the son of 4th President Sergio Osmeña Sr.; of Gerardo Roxas who was another son of a previous president; and of Benigno Aquino Jr. who was the son of Benigno Sr.. During the martial law years, it only became worse as Marcos named his wife Imelda as the governor of Metro Manila while his son Bongbong became the governor of Ilocos Norte.
