Half of Germany was, for roughly 4 decades, a soviet puppet state. With indoctrination programs, propaganda towards the western part, cadre schools, the whole deal. And even in West Germany the soviets always had a lot of support, especially in the burgeoise (yes, the irony...) upper layers of society. Socialism and communism weren't just invented here out of thin air and such.
This means that a good part of especially the general former East German population as well as the academic and cultural upper class are left-leaning (in USian terms: deep red communists), soviet/russia-supporting and antiamerican by default. This got even stronger the farther we got past the 1990s, because the view back on the communist times naturally lost the memories of the bad parts.
I always ask Germans which side of the wall they are from, it seems like East Germans are a bit more disillusioned or realistic but people from West parts can be ardent supporters of Putin
