Class, Political Orientation, and France's Rejection of the EU Constitution

The most relevant paragraph from Peter Schwarz's report on the French referendum:

According to one poll, three quarters of all wage workers, two thirds of all employees, and the majority of farmers voted “no,” while executives and academics generally voted “yes.” More than 80 percent of the supporters of the government parties (Chirac’s UMP and the “free market” liberal Union for the French Democracy—UDF) voted for the constitution, while a majority of Socialist Party and Green supporters voted “no,” in defiance of the recommendations of their respective party leaders.
