I've read that Mexico's media has questioned the source of Anaya's family's wealth. I guess those questions aren't having much of an impact in regard to concerns about corruption.
Anaya us accused of sellin an industrial warehouse to a phantom company for the equivalent of 2.7 million dollars. He argues that he bought the land when it was very cheap.
PRI accused him of being cahoots with the buyer, and that the buyer is involved in monet laundering.
All of the media has been pressured by the government to report throughly on this matter. I can say it because I direct a national newspaper.
The attorney general's office released a video when Anaya went to their offices and demanded to have a subpoena (is that the word? He demanded to be officially charged.
The illegal release of the video backfired on PRI.
PRI also leaked footage of Anaya at the wedding of the warehouse buyer, to proove they were friends. The film was illegally taken away from the buyer's house by the federal police, when they did a isearch.
It is clearly a State campaign against the candidate who said he'd have Pela Nieto and his cronies judged for corruption, and an attempt to have Meade surpass Anaya in the polls (and presumably gather the anti-AMLO vote around him).
The big winner of all this is AMLO. Anaya was moving up in the polls and stalled, while Meade did hardly win any support.
The problem is that PRI scandals are worth hundred of millions of dollars.
