I spent the 2004–2005 academic year in France, culminating with the May 29th referendum on the European Union constitutional treaty. Fifty-five percent of voters rejected it. Three days later, 62% of Dutch voters followed suit. These were unexpected results, especially in France, a country where 80% declare themselves in favor of European integration. In other member states, a simple rule generally applies: those whose priority is to strengthen the EU are on the “yes” side, while the “no” is identified with those who emphasize national interests. In the Netherlands, though the murder of filmmaker Theo van Gogh by an Islamic radical was a factor, the “no” forces won essentially because they persuaded enough people that the direction the Constitution would take the Netherlands went against Dutch interests. To do so, they played on the resentment that Brussels took their money but ignored Dutch concerns—“the same people who fooled you with the euro are fooling you now with this constitution.”
