This shows the winners of the "second vote." Dark blue = CSU (conservative party), its outlines are identical to Bavaria because this party only runs there and, this time around, won 100% of the second votes. Cyan = AfD, far right-wing party. Its outlines are nearly identical to the borders of the former GDR. Gray = CDU, CSU's sister party, making up for most of the remainder.
