France and the European constitution

The French referendum on the European constitution remains too close to call.   Early on it appeared to be a question of anxiety over cultural identity. But recent reports show that many "no" supporters are driven by economic concerns and what they perceive as an evolution from European cooperation to unbridled competition.  The French newspaper Le Monde came out against the treaty as being divisive, comparing the lack of harmonisation among states it would cause to the competition between US states in the 1920,  leading up to the 1929 stock market crash.  The newspaper argues that a lack of regulation could create a climate of cutthroat competition in which companies in low-wage Eastern Europe might undercut their counterparts in countries such as France, leading to higher unemployment rates.  With Le Monde taking a clear editorial stand againt the European constitution, can anyone doubt that it's ratification in France is in question?
