LIMA, Peru (AP) — Inside a colonial-era mansion that has seen better days, leaders of Peru’s Fuerza Popular movement gathered for an urgent meeting Thursday, scrambling for ways to save their party’s once-dominant place in politics.

President Martín Vizcarra dissolved the congress early this week and called new elections after a dispute with lawmakers over anti-corruption efforts, unilaterally eliminating Fuerza Popular’s hard-won majority in the legislature. Meanwhile, the party’s leader was already sitting behind bars at a women’s jail filled with drug traffickers and petty thieves while she is investigated for money laundering.

The dissolution of congress has plunged Peru into its deepest constitutional crisis in nearly three decades, and it may also be the start of a final, bleak chapter for the country’s most prominent political dynasty. When the legislature was last shut down in 1992, strongman Alberto Fujimori sat in the presidential palace calling the shots. Fast forward 27 years, and now it is the party led by his cherished eldest daughter that is being kicked out.

“This was a party behaving less like a political party and more like a mafia.”

When Fuerza Popular’s leaders stepped outside their headquarters after their meeting, they encountered a cruel realty: Much of Peru doesn’t love them anymore.

“You all are going to hell!” Susana Valverde, 48, yelled at a small band of women chanting slogans demanding justice for Keiko Fujimori, the former first daughter and two-time presidential candidate.

The political phenomenon known in Peru as “Fujimorismo” has seen wild ups and downs but it has always managed to rebound. This time might be different. If new legislative elections are held in 2020, as Vizcarra plans, the party will almost certainly lose its majority in congress.

“Fujimorismo has been in a death spiral,” said Steven Levitsky, a Harvard University political scientist. “It’s going to get pummeled in the election that comes. This is a pretty dramatic decline.”

The political dynasty began in 1990 when Alberto Fujimori, the Lima-born son of Japanese immigrants, won the presidency promising to usher Peru into a new era of progress. His pro-business policies, hardline anti-crime initiatives aimed at quashing Shining Path rebels and social programs made him popular with droves of Peruvians, Nancy Rios among them.

“The ‘chinito’ came in and made beautiful roads,” Rios said, using a popular nickname for the imprisoned former president. “When he arrived, this country was totally destroyed, worse than Venezuela. With him we found peace, economic stability.”

But after a decade in office, Fujimori faxed in his resignation after fleeing to Japan while facing imminent removal by an opposition-controlled congress. In 2005, he was captured in Chile and extradited to Lima, where he was eventually sentenced to 25 years in prison for human rights abuses, corruption and sanctioning death squads.

The former mathematics professor is still serving time for his role in the killings of 25 people, including an 8-year-old boy, during his administration.

Still, there were plenty of Peruvians willing to forgive Fujimorismo. Keiko Fujimori carried her father’s torch, expanding the party’s base and seeking to forge a gentler, kinder image of the movement. By many accounts, she largely succeeded.

“I’ll support the party until the day I die,” said Rios, a housewife.

In 2011, Keiko Fujimori finished second in Peru’s presidential election. Five years later, she lost again in a razor-thin vote, coming within less than a half percentage point of defeating economist Pedro Pablo Kuczynski. Fuerza Popular captured a majority in congress.

But it’s been downhill from that high point.

Constantly butting heads with Kuczynski, and later Vizcarra, its legislators have earned a reputation as hardline obstructionists for blocking initiatives popular with Peruvians aimed at curbing the nation’s rampant corruption.

“This was a party behaving less like a political party and more like a mafia,” Levitsky said.

Late last year, Keiko Fujimori was ordered jailed as prosecutors investigate accusations she funneled money from the giant Brazilian construction company Odebrecht for her 2011 presidential campaign, a dramatic fall for a woman who would have otherwise been a likely frontrunner in the next election.

Legislators whose seats are being threatened by Vizcarra’s order dissolving congress say they are prepared to fight, even as polls say most Peruvians want them out. They are devising a legal challenge in hopes of keeping congress open and avoiding a 2020 election.

“We’re not going to permit any situation in which the left takes the majority,” said Luis Galarreta, one of the lawmakers.

Party members call the president’s action a “modern coup” and say they are now in a battle to prevent Peru from becoming “another Venezuela.”

Legislator Juan Carlos González contends news media are spreading a false narrative that the party has lost public support. He noted that over 2,000 people turned out at a recent town hall-style meeting he hosted.

“The party has been declared dead,” he said. “We’re not going to stay quiet.”

Levitsky estimates Fujimorismo maintains 10% to 15% public support, and believes that although weakened, the party won’t entirely go away, particularly if it manages to forge a partnership with other right-leaning groups.

But for Peruvians like Maria Quispe, who works at a restaurant in a poor neighborhood now filled with Venezuelan migrants, the public’s relationship with Fujimorismo is irreparably broken. She voted for Alberto Fujimori in 1990, but said she cannot bring herself to vote for anyone from the movement now.

“They had a chance, but kept doing what was in their own self-interest,” she said. “There’s no way at this point that everything can be forgotten.”
