* Independent or non-party "citizen" candidacies for the 2012 federal election
* Allows for relection of federal and state legislators
* Establishes the mechanism of a popular referendum
* Mechanism for replacing the national president should he die/be incapacitated etc
* Ratification by the senate of regulatory organs
* Gives president more veto powers over budget legislation
Of course, this does not mean the reform has passed; it will now move on to the Chamber of Deputies, and then for ratification of a majority of Mexico's state governments. It is hard to keep one's hope up too high here.
But these are truly profound changes, should they be implemented.
