My personal opinion of the Peje Effect is that it was always the electoral strategy of the PRD to block the reforms proposed by Presidente Fox (while offering no viable alternatives and even though in later interviews Diputados of the PRD/PRI bloc commented they were actually in favor of the reforms but had to follow their respective parties' orders) in order to purposefully cause or allow deteriorating conditions throughout the country so that they could label the Fox Presidency a failure. IMHO, and in the opinions of many people I have spoken with about it, those Diputados are traitors to the people of Mexico by their dereliction of duty and with their eye only on personal gain, not the well-being of the country. They intentionally ignored the "will of the people", i.e. the Fox mandate, and fomented social discontent in order to claim to represent the "poor masses", who also are largely the least educated and most gullible part of the electorate. This was part of the old priista strategy of keeping the electorate ignorant and thus under control by handing out dispensas and populist social programs that actually kept the poor poor. So although I do not agree with many of the principles of the PAN, they appear to be the lesser evil as well as the least cynical and most competent of the three major parties, particularly at the national level. I see the PRD as the most cynical party and just as corrupt if not more than the PRI from which they split and to whose cause now run some of the most notorious dinosaurios along with many inept, corrupt priistas who simply live off the public dole.
Between the infamous videoscandals showing el Peje's closest associates accepting millions of pesos in suitcases (the money has never been accounted for, the officials accepting it are out of jail, and the only person still in a jail of the same DF government Peje left to run for the Presidency is the person who filmed the videos and paid the bribes), and the incompetence of the perredista governments at the state and local levels to alleviate, much less improve, ANY of our increasing problems (i.e. education, housing, jobs, PUBLIC SECURITY, ecology, pollution, public sanitation, organized crime, land invasions, corruption, lawlessness, etc) it is only asking for more trouble to vote for PRD candidates. Next to the PRD, even the priistas look acceptable.
Now we have the renegade perredista presidential candidate fomenting insurrection under the guise of civil disobedience, but it goes much further than that and includes the current violence in Oaxaca as well as the past violence in San Juan de Atenco. We also have el Peje declaring himself the President of Mexico even though he lost the election in the most transparent elections in the country's history. His is the story of a delusional demagogical fanatic seeking power at any and all costs. He represents the absolute worst of politicians, especially in this time when what we need most is national unity to overcome problems neglected for generations.
One thing is for certain: if the elections were annulled and held again today el Peje wouldn't even come close to almost winning, but would instead lose by a decisive vote against him. He completely blew the opportunity and sympathetic respect his voter turnout gave him. It has become apparent to many more people, including his former supporters, just how BAD he would've been for our country. Imagine having a President who shows contemptuous disrespect for the laws and institutions of the country he runs. In most countries such a situation has led to dictatorships. It's one thing to seek institutional and/or constitutional reform through congressional legislation (something President Fox attempted as per his electoral mandate but was frustrated by the PRD/PRI bloc), another to overthrow those institutions using mobs in the streets (something AMLO has attempted since he knew he lost the election the night of July 2).
