Ten Reasons to Watch Mexico's Presidential Election

This Sunday, Mexico will choose a new president in an election with broad implications not only for the direction of the country, but also for its relations with the United States and its neighbors to the south.

The race pits center-left candidate Andres Manuel López Obrador, often called "AMLO" for short, against center-right Christian Democrat Felipe Calderón Hinosa. Obrador led most polls through March, when an aggressive campaign brought Calderón ahead in some surveys by a slim margin. The Los Angeles Times reports that the two are now in a statistical dead-heat (Obrador had a two-point lead in two major polls released last Friday, but that's within the margin of error for both polls.)

Calderón is a member of the National Action Party (PAN), the party of outgoing President Vicente Fox. He served previously as Fox's energy minister. Obrador's Democratic Revolutionary Party (PRD) leads a coalition that includes several small parties of the left.

Robert Madrazo, the Institutional Revolutionary Party (PRI) candidate trails a distant third.

Also at stake are 628 seats in Mexico's bicameral legislature, as well as the government of Mexico City.

Here are 10 reasons to watch this race:

10: The democratic revolution continues

The PRI held a virtual monopoly on power for over 70 years, until electoral reforms in the 1990s brought competitive elections to Mexico. Vicente Fox's win in 2000 was the first for an opposition candidate.

9: In terms of running an election, Mexico puts us to shame

A close look reveals much for Americans to admire. Election day is Sunday -- as opposed to a work day -- a long-sought goal for electoral reformers here in the United States. In 2000, Mexicans turned out at a 13 percent higher rate than Americans. It will be interesting to see how much of that difference was due to the novelty of the country's first truly open race.

An independent electoral commission will run the vote instead of partisan hacks. No Florida 2000, no Ohio 2004.

No Mexican will have to cast a ballot on paperless electronic voting machines. Paper ballots will be used in a uniform nationwide system. Mexican voters are issued fraud-resistant ID cards

8: Campaigns receive public financing

One of the most important reforms of the past decade was the advent of extensive public financing of campaigns, significantly lowering the impact of special interest cash. All major parties received $60 million (U.S. dollars) in public funds for the campaign, and total spending is capped at $80 million.

7: The electoral institutions are squeaky clean

Observers from across the political spectrum have lauded the efforts of the Federal Election Institute (IFE) to ensure a clean vote. José Salafranca, head of the EU's observer mission, told Inter Press Service that Mexico's electoral institutions are now among the most reliable and trustworthy in the world. Chuck Collins, a senior scholar at the Institute for Policy Studies, told me by phone from his Oaxaca home that there's a sense of calm leading up to the polls, a sea-change in a country where elections have often been marked by blatant fraud and political violence.

But Mexico's party operatives may not be as clean as its institutions. The Washington Post reported that independent election observers have accused all three parties of buying votes, especially in poor rural communities. Federal election officials, while acknowledging that vote-buying is an issue, say it won't impact the outcome. Nonetheless, expect aggressive challenges if the tally is as close as polls suggest, especially if Obrador wins by a narrow margin.

The monitors say that the PRI has been the most aggressive in vote-buying and a surprise win by Madrazo -- who trailed the leaders by 7-9 points in the latest polls -- would likely spur popular protests or strikes.
