Mexico's Ruling Party Secures Governorship in Populous State.
Mexico's ruling party, Morena, won the governorship of the State of Mexico, the country's most populous state, dealing a life-threatening blow to the old ruling Institutional Revolutionary Party (PRI), which had governed the state without interruption for nearly a century. The PRI managed to hold on to the governorship of the sparsely populated northern border state of Coahuila, but the loss of the State of Mexico could spell the end of the PRI's political relevance on a national stage. Morena now governs 22 of Mexico's 32 states, and is considered the frontrunner in next year's presidential elections.
