X-ref: JakeS' comment, above, I don't quite see why the Center or Liberal Parties have to go along if they can cut a better deal.  Either with the Social Democrats -- who are, after all, still the largest party -- or the Moderates since the Greens, Center, and Liberal parties, together, control the next government.  The last two may have wedded themselves so firmly, tactically or ideologically, to the Moderate controlled Alliance that they can't wiggle out, I don't know the answer to either question.  

The Center and Liberals have an "out" since they can always claim they are not going to be in a government that relies on the Swedish Democrats.  How far & well can that Play?  shrug Don't know.

In fact the entirety of my ignorance is stunning.
