How has the mainstream media been able to disguise the war of liberation in Mexico as a drug war for so long?

It's obvious to even the least savvy observer of the violence in Mexico that it is not a drug war carried out by criminals but a war of independence along the lines of Poncho Villa...The Mexican people have been oppressed for so long that it's amazing that it has taken this long for them to rise up and overthrow their corrupt government and create a Hugo Chavez type Social Democracy...
