I have argued on this site that the last thing America needs is European style government-by-demonstration, and that the massive street demostrations over illegal immigration perhaps were a signof the Left’s intention to import exactly that style of guerilla theater politics into America. Now Mexico seems poised to illustrate that point: the free market candidate for president is leading the pack. According to the WSJ, but the two leftist parties are threatening to disrupt society and dispute the election if he wins:

On July 2 Mexico will hold the most closely contested presidential election in its history. That in itself wouldn’t be a problem if all the candidates mitted to the democratic process. But in recent weeks two of the three main campaigns have jointly pledged to challenge election results in the streets with massive unrest if their candidates don’t win. If that happens, Mexico will be thrown into chaos and Mexicans will be the losers.

A poll by Zogby International last week gave Felipe Calderón a five percentage point lead over Andrés Manuel López Obrador and 12 points over Roberto Madrazo.

That’s good news for Mexico. Mr. Calderón of the National Action Party offers the best chance to deepen the market-oriented economic reforms necessary for strong growth and job creation and to ease the exodus of Mexicans abroad. Mr. López Obrador of the hard-left Revolutionary Democratic Party, on the other hand, would return the country to nationalist populism and a closed economy. Mr. Madrazo of the Institutional Revolutionary Party is marketing a mixture of both, publicly siding with the left while privately pledging support for centrist reforms.

Yet even if Mr. Calderón can hold the lead, Mexico may be heading for trouble. The PRD and the PRI have announced that they are forming a united front to reject the election results if neither one wins….

This situation would weaken the country’s institutions, raise uncertainty and fears of anarchy, with potentially serious financial instability and economic disarray. Emigration would mushroom. The long awaited Mexican miracle of fast growth and job creation — stemming migratory outflows — would be lost for at least another six years, if not for much longer.

This would be a disaster for the entire hemisphere. Americans can only hope and pray that Calderon wins by a wide margin. As Hugh Hewitt is wont to say, “If it ain’t close, they can’t cheat.” Let’s hope it isn’t close.
