Mexico’s former ruling party could face near-extinction in Sunday's governorship election in the State of Mexico, the largest of Mexico’s 32 states and the last large one governed by the old Institutional Revolutionary Party, the PRI.
The race could also mark a high point for President Andrés Manuel López Obrador’s Morena party, which has imitated — and largely replaced — the old PRI across the rest of Mexico. Nearly five years into his single six-year term, López Obrador remains highly popular.
