The PvdA is in hot waters after the elections and after their decition to take part in the new Government with the CDA and CU. Part of the problem is the SP and the other part are the overrated expectation of the party members and the public.
The public (the voters) expect instant change and expect that any ellection promise will be filled in. The PvdA is part of a coalition and that means that vou always get what you want. The SP is doing well in this situation, they walked out of the negotiation to take part in the government, they can bash the PvdA about the promises they make during the elections and get away with their support of Geert Wilders around the double nationality issue.
The PvdA party members want Bos to either to drop his function of partyleader or get out of the government. I think he should stay where he is and get to work. The party members should focus on how to win back the voters and shut up.
