The run up to the referendum has been very mutit you have a president who has no political party, no political apparatus around him. The main trade union, which is a very powerful force in tunesian politics, hasn't taken a position on this. Turn out has been falling since the revolution. It seems likely that the constitution will pass, if only for lack of a norganized no campaign. If it passes, it will probably be with low turnout. And therefore a small minority of tunisians who are approving this.
