MEXICO CITY (AP) — Mexico’s president feels his citizens don’t care as much about their nation’s history as they should. But his effort to change that may trigger a historically negative response. Andrés Manuel López Obrador is floating a plan to ditch three-day holiday weekends. The plan would end an arrangement similar to how holidays like President’s Day and Memorial Day are handled in the U.S. They’re observed on Mondays, creating a three-day weekend. López Obrador is a history buff who was irked because few Mexicans seemed to know yesterday was the anniversary of the adoption of the country’s constitution. Mexicans have gone online to protest the proposal.
