Yep and its probably gonna stay that way. You can apparently still see differences in voting behaviour, happiness and life expectancy between both sides of the Roman Limes wall.

it’s that plus a population map to some extent, with the large population centres as usual leaning more left.

Yeah, the AfD is the nazi party. Nazis happen when people are in a bad financial situation. And former East Germany still is in a worse financial situation than the West, hailing all the way from being looted and isolated after the war, to young talents moving into the West to find jobs after the reunion happened.

There’s also an argument to be made that not many immigrants move to the rural areas in the East, because well, if you’ve got the choice, why move there? As such, it’s a lot easier to rally people there with racist talking points.
