Notice that they totally ignore that die Linke is no longer an east only party.  I'm suspicious of exit polls, particularly if there's postal voting.  Any good campaign organization on the left is going to push their people to vote by post if at all possible.  That way you get out the disabled and elderly, who tend to be supportive of things like pensions and government aid.  Plus I wonder if there will be a large group of Hartz IV people who show up in the postal vote.
