The comparison doesn’t work. In the US it is common practice that a newspaper gives a recommendation.
Also the US has a two party system. Compare this to Germany’s multi party system. If you are undecided between to options a recommendation might help. If you are undecided whether you should vote the Greens or SPD a newspaper recommending CDU doesn’t help you at all.
While it is not illegal for a newspaper to give a recommendation in Germany, it would be a scandal indeed. But the only reason for this would be that they didn’t do it before. People are just complaining about changes like in this case as well
Would I be wooshing myself if I told you you did?
