The old guard of the PRI retaliate against the increasingly open new party leadership, which up until that point had been winning the elections by smaller and smaller margins. The PRI candidate, Francisco Labastida, is put through a heavily rigged election amidst strong domestic protest, "defeating" Vicente Fox. The election is, of course, contested and heavily condemned by the world media. Further condemnation comes to the party after Labastida turns out to be a terrible leader. The economic woes of the Zedillo years continue unabated, the increasing privatization and neo-liberalist trends leads to increased economic imperialism and lower standards of living, while corruption runs rampant and deals are again being made with narco lords.
Throughout Labastida's term the country is in turmoil. Out of this chaos, and especially in response to the rampant privatization, the Labor Party, led by Alberto Anaya, finds great popularity. The first sign of this backlash occurs in 2000, soon after Labastida's election, when Anaya on the PT ticket wins the gubernatorial election for the state of Morelos. Anaya's programs of public welfare and de-privatization in the state begin to greatly improve the economy of Morelos, and the PT soon becomes the main icon of the anti-PRI movement.
In 2006, at the end of Labastida's presidency, Anaya runs a vigorous campaign throughout the country to unite the people against the PRI and behind the PT. Many who would have thrown in their lot with the PRD instead join the PT, and several Mexican far left parties, including the PRD, negotiate a coalition with the party.
Anaya's election to the presidency has been called the "September Revolution", and represents the ignominious fall of the PRI and the celestial rise of socialist and Eurocommunist tendancies in Mexican politics. The Communist Party of Mexico is renewed and manages to score 5 seats in the Chamber of Deputies and 2 in the Senate, while the PRD also becomes a major force. Under Anaya's administration, Mexican oil is renationalized under Pemex, Telemex and Azteca are renationalized, and state welfare is reinvigorated. After years of deals with drug lords, the Mexican government begins serious efforts to curb their influence and activities using military force when necessary. The Mexican political apparatus is democratized and the 1917 Constitution reinvigorated with several equal rights amendments and economic statutes.
The enormously popular PT and its allies would win again in the 2012 elections against the broad "Nationalist Coalition" led by the PAN.
