SAN JUAN, Puerto Rico — Puerto Rico Rep. Jesús Manuel Ortiz defeated Sen. Juan Zaragoza in a gubernatorial primary held Sunday by their Popular Democratic Party, which seeks a return to power in the upcoming general elections.

Zaragoza conceded defeat after obtaining 38% of the votes to his rival’s 62%, even though only a little more than 60% of the votes had been counted.

Meanwhile, Gov. Pedro Pierluisi was still locked in a battle against Puerto Rico congresswoman Jenniffer González in a primary held by the pro-statehood New Progressive Party. The two ran on the same ticket four years ago, but González announced her plan to challenge Pierluisi in early December.

All candidates face disgruntled voters on an island still struggling with chronic power outages and awaiting completion of reconstruction projects following Hurricane Maria, which hit as a Category 4 storm in September 2017.

Other ongoing complaints include the difficulty of obtaining business permits, a fractured education system and the lack of access to capital markets after the local government emerged two years ago from the biggest U.S. municipal bankruptcy in history after announcing in 2015 that it was unable to pay its more than $70 billion public debt load. The debt was accumulated by governments that overspent, overestimated revenue and borrowed million despite a ballooning debt.
