In an interview with the Spanish El Pais, AMLO said he had forgiven Calderón for the 2006 election, and that he would not seek to reopen any investigation into that election, because there is already a "verdict." Which one is that, one might ask?
He also notes, "I've evolved, I have more knowledge of the reality because I have traveled the country," though he doesn't really tell us what new lessons he has learned, or any self criticism made. I would really like to have seen some.
In any case, the interview is well worth a read.
