It wouldn't stop you. The united states is like that. We have federal laws which apply everywhere but all 50 states have their own individual laws with their own penalties. We also have all sorts the different cultures all mingled in together here. It is far from impossible and is very realistic for Europe to be one country.

If I knew what the EU constitution that is being proposed was about then I would call stupid or good vote on this one...but since I don't I will not say. If it was more about market laws over setting up a federal type government...I understand. The EU was suppose to be a step towards easier trade in Europe and it has accomplished that but because it was suppose to be about trade and economic stuff it really doesn't suprise me. I wish it had been more about a federal government.

Something tells me that the majority of people who voted had no clue what the constituion contained though and just didn't like the idea of losing their power.
