Why can't they take NO for an answer?

What does this say about democracy in Europe when they can't take no (regarding the EU constitution) for an answer?

In Brussels and some national capitals, officials are exploring ways to circumvent the “no” votes and continue the drive for ever closer union. The first plan is to find a way to bypass the French and Dutch rejections, and ratify the treaty anyway — either through renegotiating it or resubmitting it for a second vote.

After the French result on Sunday evening, Jean-Claude Juncker, the Prime Minister of Luxembourg, which holds the rotating EU presidency, and José Manuel Barroso, President of the European Commission, plan to lay out the course ahead at the Commission’s Brussels headquarters.

Mr Juncker will declare that the ratification process must continue, and that countries such as Britain must not abandon their referendums.

Mr Juncker insisted this week: “The countries that have said ‘no’ will have to ask themselves the question again.”
