I don't see that anything has really changed. The PD's weren't an essential component of the coalition, it could have been formed without them, indeed it might have been easier to negotiate with the greens without PD involvement, so it's not as if she had to do too much negotiation/pushing to get the health portfolio.
I suspect Biffo will keep Mary Hearney in health - who else would want it & given that Michael Martin already had a bash at screwing it up nicely, then I think other FF members will want to keep their noses clean for the next election.
