Who rules in Mexico

This article describes the different theories on how the Mexican bureaucratic system works with two main themes. One is that all decision making flows upwards in a hierarchy with an elected president at the top; the variation between the theories in this regard is how much does the president rely on underlings to inform him on his decisions and how much outside influence determines his decisions. The second theme is that corruption is very much the system in Mexico, that the mexican government works with corruption efficiently.
