I agree with Senator Xenophon—they should. But these days the Senate has become very boring. These days in this chamber the government has got the numbers. What happens from time to time is that the Greens—playing to the gallery, playing a bit of theatre—will jump up and down and say, 'We don't like this,' or 'We think this is bad,' or 'The mining tax should be expanded,' or 'We think we should do this and that,' but at the end of the day they will turn around and have their tummy tickled by Julia Gillard and on they will go. They will vote for it. They even vote for the gag these days.
