Forgive me if I'm about to ask some dumb questions.  So there are only two districts -- Brussels-Halle-Vilvoorden plus the two districts mentioned in note 2 -- where both the Flemish and Walloon parties are on the ballots?  Do the ideologically aligned parties from the two language groups automatically caucus together, or form coalitions?  Isn't there a small German-speaking community, and where do they fall in the electoral geography?  Why are the polls in Brussels only among the French-speaking community?

Now for non-logistical question... why has the PM not been able to govern effectively?  Because that seems like quite a dramatic drop in popularity.

Sorry to pelt you with questions, but as I said, I think the system is really interesting, and I know not very much about it.

Thanks again for the diary!  And here's hoping that it won't swing too far rightward.
