Which party "won" which state in the German federal elections from 1949 to 2017

[buritobr]

Since Germany doesn't have a "winner takes all" rule like the Electoral College in the US, the winning parties in the states doesn't matter too much, but it is interesting to see which party had the plurality of the Zweitstimme in the federal elections.

Observations
Unlike the USA since 1992, there are few states in Germany which always vote for the same party. If a party can have a good national margin, this party wins the majority of the states.
The few safe states are the conservative states in the south and the social democratic city-states. The CSU always won Bavaria, the CDU always won Baden-Württemberg, the SPD always won Bremen, the CDU won Hamburg for the first time only in 2009. The CDU can win Berlin because the left-wing vote is split between SPD and Linke. Bremen is the unique state in Germany the CDU never won... and Bavaria too.
The Linke and AfD have already won states in the East. The FDP and the Greens never won states. In early 2021, we could think that th Greens would win in at least one state this year. But not...
In the US, the map ever repeated. In Germany, 1957 and 1983 had the same map. 2002 and 2005 too.

NRW used to vote strongly on the left of the country between late 1960s and late 1990s. Not in the early years of the FRG. Maybe because of Konrad Adenauer.

do we have the strongest performance for each Land? did CSU ever break 70% in Bayern? CDU 60% in BW? SPD 60% in Bremen? etc.

From 1949 to 1987, you can see all the results by state in the Wikipedia auf Deutsch https://de.wikipedia.org/wiki/Bundestagswahl_1949

From 1990 to 2017, after the reunification, you can see all the results by state in the Wikipedia in English https://en.wikipedia.org/wiki/1990_German_federal_election

Nordrhein-Westfalen in 1949
CDU 36.9%
SPD 31.4%
Zentrum 8.9%
FDP 8.6%
KPD 7.6% (only a little smaller than Linke 2009)

In 1949 there was an attempt to rebuild the Weimar Republic party system. There was the BP in Bavaria, which didn't perform much worse than the CSU and the SPD.
The 5% barrier destroyed everything in the following elections and Germany had a 3 party system before the 6 party system.
