I voted yes on Maastricht 1 and no the second time around on the basis that I was annoyed that the first vote was ignored.
Even if I had voted yes to Lisbon 1 (which I didn't) I'd be voting no now for the same reason I voted no to Maastricht 2.
i would agree with this if nothing had changed. I voted yes the first time round and would vote no if they presented us with the same treaty in the same context as they did before. But...things have changed. They have legal assurances now to assuage people's concerns about the treaty, so that's not really a good enough argument to vote no anymore.
