Midterm Elections: Morena Emerges, PRI Weakened

Midterm federal elections saw the PRI retain a plurality but with a significantly reduced margin. AMLO's new Morena party (founded October 2014) won Mexico City Federal District delegate races and established itself as a genuine third force in Mexican politics. The elections demonstrated growing discontent with Peña Nieto's government amid the Ayotzinapa crisis and Casa Blanca scandal.
