Still not good enough, and depressing that a third would vote for the party that's mainly responsible for Germany's problems today. But midterm polling in Germany - both at the federal and state level - is more useless than current US presidential polling. There has always been a strong shift towards in the incumbent in the final weeks of a campaign. Schröder also trailed for the most part of his term, even by twenty percent and more and still pulled it off in 2002 and came pretty damn close in 2005.
Are you writing this again and again because you really believe Scholz can do this or simply because you have to be optimistic as an SPD member??
