The signing of the Lisbon agreement yesterday will end the public’s ability to vote on continuing with the movement toward an EU Constitution. It has been obvious for many years that the leaders of the EU don’t want to have the public vote on the direction the EU is taking.
The liberal members of the EU worry about having a revised referendum voted down by any country. So they don't want any further public unhappy opinions to be displayed by a negative vote. If this passes (they still have to ratify it) you can forget voting.
