Dutch Elections House of Lords”: SP biggest winner

Again the SP is the biggest winner in a Dutch election. This time the election for the provincial government who elect the first chamber (= house of lords). The leader of the SP, Jan Marijnissen, is almost as popular as Pim Fortuin is his days. His message is as populist and as conservative even when he is leading a Socialistic Party.

The question is: when is the man is the going to deliver? He walked out of negotiations for a role in the new government (he says they others didn’t want him but that is very questionable).
I think he is running the risk that in four years time the people are going to say, we voted for you but you didn’t do anything, and his popularity is so massive that nobody notices and sees the number two three and four in line.
