A sense of déjà vu

I have a severe case of a sense of déjà vu. It's like you know when there is a Conservative Party conference on the horizon and lots of Tories start running around being eurosceptic, trying to assure everyone that this time they will actually do something because they are the people who are the real eurosceptics. Been there, done that. Comes the dawn, Parliament sits again and ...... the voices grow dim, the votes do not materialize and things return to normal.
