Andres Manuel Lopez Obrador (AMLO)

Much has been made of US President Donald Trump’s potential impact on Mexico, but one critical story has been largely ignored in the Western media.

Coverage of Mexico in the Trump era has been dominated by speculation over the fate of the stumbling Mexican peso, the possibility of the North America Free Trade Agreement (NAFTA) collapsing and, of course, the wall.

Meanwhile, a seismic shift is quietly taking place in Mexican politics: the right wing is the weakest it has been in generations, while the left is seeing a historic resurgence.

The leftist political party led by two-time former presidential candidate Andres Manuel Lopez Obrador will govern in areas representing more than 8 million people after Mexico's June 7 elections. Lopez Obrador's National Regeneration Movement (Morena) took part for the first time in the mid-term elections. It won in six of the 16 districts of Mexico City, breaking the long-time hegemonic rule of the once popular Democratic Revolution Party (PRD) in the country's capital, which won five.
