What is PDS? Do you need to get 5% to win seats? If so, how come PDS has two? PDS are the former east german communist party.
They get to keep their two seats, because they were won in theri own districts through a direct vote (kind of like one of our representatives).
The 5% only means, that the party wont be able to send candidates from their list (indirect vote)
PDS is the "Partei des Demokratischen Sozialismus" aka Party for demokratic socalism. The Left-over of Eastern Germany's communists. They can have individual seats (direct votes) even if they are below 5%
