In French Elections, Sound and Fury From the Left's Mélenchon Jacques Brinon/Associated Press Jean-Luc Mélenchon, the far-left candidate, is now running third in many polls in the crowded contest for president of France. PARIS - They sang "The Internationale," carried red flags and shouted "Resistance!" They booed whenever the word "rich" was pronounced, and they applauded when their leader, Jean-Luc Mélenchon, called the far right "professional racists" and the Socialist candidate "a pedal-boat captain." The crowd of more than 20,000 who gathered in Lille, close to the Belgian border, feel no nostalgia for the Soviet Union. They call themselves militants of the Front de Gauche (the Left Front), a coalition of the far left built on the remnants of France's once-powerful Communist Party. Disappointed by the mainstream candidates and enthralled by the fierce and witty language of Mr. Mélenchon, they have been joined by many of the angry and jobless, young and old, who say they feel unprotected in the face of the economic crisis. And Mr. Mélenchon is now running third in many polls for the French presidential elections this month. With the first round of voting two weeks away, the far left is running just ahead of the far right of the National Front and its candidate, Marine Le Pen. Together, those on both wings of the French spectrum, who share strong criticism of globalization and the European Union, could take 30 percent or more of the vote in a race with 10 candidates, which would be more than either President Nicolas Sarkozy or the Socialist candidate, François Hollande, the two front-runners. And how the voters on the so-called fringe choose to cast their ballots in the second-round runoff on May 6 is likely to decide the race. Mr. Mélenchon, 60, a former teacher, Trotskyist and minister in a Socialist government, resplendent in his trademark red necktie, has been the surprise of this election so far, and he has been gathering some of the largest and most passionate crowds to his rallies, in Lille, Paris and most recently, Toulouse. He speaks of "civil insurrection," raising the minimum wage 20 percent to $2,200 a month, confiscating all income above $470,000 a year and banning profitable companies from laying off any workers. "When there is no more liberty, civil insurrection becomes a sacred duty of the Republic," he often declaims. "If the crisis were stronger here, as it is in Spain," said Stéphane Courtois, a historian and expert on the Communists and the far left, "Mr. Mélenchon would now have 25 percent of the votes." Mr. Mélenchon created the Parti de Gauche in 2008, then the Front de Gauche as a catchall of former Communists, Trotskyists, anti-capitalists, environmentalists and Socialist dissidents like himself, who feel the Socialist Party and Mr. Hollande are too centrist, consensual, establishmentarian and "soft." Communists make up more than 80 percent of the members, but Mr. Mélenchon's appeal has spread far beyond the card carriers to touch an angry, disappointed nerve in France that has also fed the National Front. He has been leaching support from Mr. Hollande, who has been running a timid campaign, and threatens to pull the Socialist candidate into second place in the first round, behind the unpopular Mr. Sarkozy. Mr. Mélenchon, a lover of philosophy and of the novels of William Faulkner, is a stirring, amusing speaker, capturing the attention of his audience through his erudition and his coruscating humor aimed at bosses and bankers. He has branded himself "the sound and the fury," after Faulkner's most famous novel, and plays on the edge of demagogy, his critics say, with no regard to how much his proposals could cost. "Once again, you will have to be the crater from which the new flame of revolution erupts," he told his supporters in Toulouse, "lighting the fire of contagion that will become the common cause of the peoples of Europe." "If Europe is a volcano," he shouts, "France is the crater of all European revolutions!" He is a descendant of the 1968 student-worker riots in France who has moved through the Communist and Socialist parties before creating his own. He was the minister of vocational education from 2000 to 2002 under a Socialist prime minister, Lionel Jospin. In 2005, he strongly opposed a failed referendum on a European constitution, and three years later quit the Socialist Party and his senate seat. He remains a member of the European Parliament.
