Obrador became Mexico City’s mayor. After more national exposure, he entered the 2006 presidential election, representing a PRD-led coalition of center-left parties. Obrador’s “Coalition for the Good of All” appeared to be winning until he was declared to have lost by 0.58 percent. That led to a massive takeover of Paseo de la Reforma and the Zocalo plazas in Mexico City, where protests endured for months.
I watched that election cycle quite closely. It was a real shame what happened.
Obrador may well turn out to be the best leader Mexico has ever had. I wouldn't be a bit surprised by it. In fact, I rather expect it.
