Mexico's President-elect Enrique Pena Nieto, right, of the former ruling Institutional Revolutionary Party (PRI), right, alongside Jose Luna Ramos, president of the magistrates of Mexico's Federal Electoral Tribunal (TRIFE), holds up a document issued by the TRIFE that declares he won the majority of votes in last July's presidential election in Mexico City, Friday, Aug. 31, 2012. Pena Nieto will be sworn-in to office on Dec. 1.

The following editorial appeared recently in the Los Angeles Times:

The Institutional Revolutionary Party's Enrique Pena Nieto has twice been declared the winner of Mexico's presidential election, yet the runner-up, Andres Manuel Lopez Obrador, refuses to recognize the results. Instead, the leftist candidate is preparing to hold a demonstration Sunday and threatening to establish a kind of shadow presidency, just as he did in 2006, when he narrowly lost that vote.

That's unfortunate. Mexico can't afford the kind of long and divisive battle that Lopez Obrador is threatening to wage. The country is mired in a drug war that has claimed more than 50,000 lives since the military was sent into the streets to combat the country's narco gangs. Corruption is rampant, judicial reforms remain on hold and the economy is sluggish.

No one disputes that Mexico's electoral process could use improvement. But if Lopez Obrador believes the electoral system is broken, he should work within the political system to fix it. A good place to start would be to craft specific reforms and then press Pena Nieto to enact them. Staging street protests, however, will only serve to undermine the electoral process and prevent the new government from moving swiftly to tackle the problems facing the country.

There were allegations that some groups distributed gift cards to poor voters, presumably to sway their vote — and those allegations should be investigated. But there is no evidence that widespread fraud cost Lopez Obrador a chance at the presidency or that the electoral tribunal that reviewed his appeal is a corrupt body, as he has suggested. In fact, the seven magistrates that serve on that court are nominated by the country's Supreme Court, confirmed by Congress and widely seen as credible, and international observers, including the Organization of American States, praised the July 1 election.

Lopez Obrador may well believe he's helping to protect democracy in Mexico by demanding recounts and challenging its institutions. But what he's really risking is becoming an irrelevant voice in the political debate. If part of becoming a modern democracy requires clean and transparent elections, then it also requires that candidates accept the outcomes of those elections.
