If you'll notice, SPD has almost completely disappeared from areas of former West Germany (BRD/FRG) while going up in former East Germany (DDR/GDR). CDU seems to have made some inraods East as well, but still retains it's stronghold south (Those funny Bavarians
Friesland, Heidesheim and the Ruhr-Essen-Dortmund remain SPD strongholds.
I found it interesting that the Greens managed to capture a district in Berlin (look for the odd green coloured tome in the enlarged map of Berlin). The Greens have taken over Stadtkreise Berlin-Friedrichsh.-Kreuzb.-Pr. B. Ost
Always been strong there but this is the first time they've taken the district.
