Well, if it is just changed a bit and or a new vote is held etc., results could change. That is why even though one has already rejected it, it may not be the end.
Ah, they just voted against it before they voted for it. Now I understand. ;=)
BTW, I do recognize that there may be another version of the constitution proposed. But the death of this constitution is not likely but certain. (Assuming that things proceed as agreed upon--which I admit is not always how it happens in Europe. That is why I said "European logic.")
