As best as I can see ASOC, the Mexican federal government is trying to play the entire Lopez Obrador protest movement down, but this particular challenge is quite new -- it was just put up at 8:19 p.m. Central Time -- and there has been no official response as of yet. The Federal Preventive Police have come out in force to keep the protestors off the grounds of the national legislature, where they have planned to disrupt Vicente Fox's scheduled September 1 address to the Mexican people, which is something similar to the "State of the Union" address our President gives every year. But I do expect to see some kind of commentary from President Fox in this regard, as well as an extension to many of the prominent political players in Mexico.
I'll keep an eye on it and notify the board when I see anything significant.
And by the way,
September 16 is Mexico's El Grito de la Independencia, Mexico's true "Independence Day," though they also celebrate Cinco de Mayo in a similar fashion. Basically the 16th of September is the celebration of their independence from Spain and Cinco de Mayo celebrates their great victory over the French in 1862. Lopez Obrador is obviously "working the calendar" to select a day when there will be lots of people in Mexico City to boost attendance at his planned "convention."
