Mexico is holding its first ever judicial elections, which have sowed confusion among voters as they struggle to understand a process set to transform the country's court system.

But the president of Mexico's opposition party, Partido Accion Nacional (PAN), called the election a fraud. On social media , Jorge Romero Herrera blasted Sheinbaum for low voter turnout.

In a recent poll that Ms. Sheinbaum mentioned in a news conference to try to show support for Mexico’s experiment, 72 percent of about 1,000 voters surveyed said the judicial election was needed.
