I feel weird

While in France a BIG debate is presently going on about the European Constitution (a referendum will be held on this point on May 29th), I can't help but feeling weird.
According to recent polls, the "NO" in France to this European Constitution may be the winner of the referendum. Of course, as an European, I will vote "YES" for this constitution because this text which has been written in 3 years by Europeans of different countries, cultures, political regimes, political organizations, blabla, is a real chance for Europe. It will allow the EU (25 countries) to function properly and it's the first time a real POLITICAL aspect is added to the economic side which has always been privileged before. Anyway, 55% of the French voters are likely to vote NO...and especially those who define themselves as left-minded. And the majority of the right-wing voters are likely to vote YES. It's the first time I feel myself more on the right-wing side...Of course, a lot of leftists are going to vote YES as well but still...I feel weird about that.
A lot of left-wing politicians are fighting against this constitution. I don't get it: according to them this consitution is liberal. Excuse me? This consitution recognizes a lot of social rights, such as the right to strike, that even the French constitution does not recognize... I feel it's just a very selfish way of obtaining some advertisement.
A bizarre thing is also the fact that extremist left-wing parties and extremist left-wing parties are all fighting against the European constitution (with different arguments though). But this only fact is enough for me: this Constitution represents progress and liberties and, as usual, extremists could not agree with this... This point by itself legitimize this constitutional text for me.
I WILL VOTE YES!
