Much talk of the comments allegedly attributable to Andrés Manuel López Obrador, reported in Reforma, where he says that no matter what, he will be a 2012 candidate, either of one, two, or three parties. I have for a long time believed (and so has Joaquín López-Dóriga), that there is no way AMLO will not run in 2012, regardless of any agreement with Marcelo Ebrard.
Speaking of PRD caudillos and presidential campaigns:
Cuauhtémoc Cárdenas, the man who enticed AMLO to leave the PRI only after the 1988 fraud and only aftr PRI had denied him the PRI candidacy for governor of Tabasco in the fall of 1988, opined that he does not support the idea of a national poll to decide who will be the PRD's 2012 candidate, preferring instead some kind of party vote. I am repeating myself ad nauseam here as well, but I remain convinced that he still is far from giving up the idea of another Cárdenas as president of Mexico.
