happened in Mexico City to AMLO in 2000.
Did it? I don't recall - I had just moved to Mexico City around then, but wasn't yet reading the local papers. Seems strange: he took over from his fellow PRD members: immediately before him the mayoralty was held by Rosario Robles, who took over when Cuauhtemoc Cardenas resigned to run for the presidency. As this was long before Cardenas and Lopez Obrador started major bickering, it would seem not clear why cardenistas would be out to screw Lopez in any serious way. Though, of course, I could easily believe that back at the time Cardenas didn't know what an e-mail was - he doesn't strike me as a computer geek, to put it mildly ))
you're right, I misremembered.. I was thinking about the '97 transition to CC rule: see the chapter called "Left City" in John Ross'
'El Monstruo: Dread and Redemption in Mexico City', which I likely read on Nov 6 2010.
