Still, Imelda’s moment of reckoning was relatively short-lived. After five years of comfortable exile in Hawaii, she was acquitted of racketeering and fraud charges in the United States. She returned to Manila in 1991, two years after Mr. Marcos died. By then, with few improvements under the new, democratic government presided over by Mr. Aquino’s widow, Corazon, many Filipinos were already nostalgic for the Marcoses’ firm hand. She ran unsuccessfully for president in 1992 and 1998. Yet in 1995, she snagged a seat in the national Congress and ran and won again in 2010. Earlier this week, she announced her plans to seek another term.
