This article draws on two research strategies to analyze the radicalizing effects of "Sarkozyism" in France. The first uses the computer program ALCESTE to compare systematically the presidential campaign discourses of Jacques Chirac and Nicolas Sarkozy as a way to evaluate how Sarkozy has altered the ideology of the French right. This analysis shows that a radicalization of the French right has in fact taken place with regard to questions of immigration, national identity, and sécurité. The second strategy makes use of the sociology of labeling to analyze expressions of "anti-Sarkozyism" on the internet. A cartographic study of the web sheds light on the variety and dynamism of this anti-Sarkozyism, and in so doing helps us take the full measure of Sarkozyism's strong polarizing effects.
