Yeah....I think I read somewhere that the meaning of "conservative and liberal" are completely reversed from the way we use those same words..(?)
The CDU has been the traditional center right party (a la GOPe). SPD has been the center left party. The Greens are essentially the Obama Administration and the AfD is the new right party opposed to refugees, the EU bail outs and the tax burden.
Not reversed. Sideways. More similar to pre-Goldwater and pre-FDR definitions.
