The latest French opinion poll gives French President Jacques Chirac a potential landslide 81 percent of the vote in the May 5 runoff for president. Controversial far-right leader Jean-Marie Le Pen is on 19 percent -- just two points higher than in the first round. The news of Chirac's huge lead -- 61 points up on his first round showing -- came as hundreds of thousands of anti-Le Pen demonstrators took to the streets all over France in the largest protests against the National Front chief to date. The survey by CSA polling group, published in the newspaper Le Parisien on Saturday, put the number of abstentions or invalid votes at an unusually high 29 percent.
