The day after Corrente brought you the actual video, the The Houston Chronicle writes a story:

The videos — one of which shows a man apparently stuffing wads of votes into a ballot box — are part of a strategy by the former Mexico City mayor to overturn the election results.

Meanwhile, the Federal Electoral Institute, which Lopez Obrador says helped steal the elections, launched radio ads to defend its reputation for fairness. The ads say the voting was overseen by 1 million citizens and that all five competing political parties had observers at most of the voting booths.

Lopez Obrador says his Democratic Revolution Party only had observers in 70 percent of the 130,000 polling stations.

I'd say that Obrador makes a good prima facie case with that response. After all, if you were going to steal something, you'd want to do it where you weren't being watched.

However, it would be interesting to know if the videos came from a station where Obrador's party didn't have observers. And it would also be interesting to have a statistical breakdown of the where the irregularities took place. Do they correlate to the places where Obrador didn't have observers? (The north, perhaps?)

Now, to be fair--and here at The Mighty Corrente Building, "Foily But Fair" has ever been our motto, carved in gold letters round the pediment of the massive dome of the Borges wing in the Library Department--the FEI's response to the videos (search on "square 2227" here , as prompted by alert reader Julio)--is not directly addressed by the Chronicle article.

Or by any other article in the English press.

So, all we can do is track the events as they unfold, and try to get as much detail as possible.

UPDATE Obrador press conference on where the videos came from. Not all the questions above are answered.
