Yes, Lindner is in a difficult situation right now. He had probably thought that as Minister of Finance, he would be the power behind the throne (like Schaeuble was between 2009 and 2017) and now he is doomed to watch Habeck/Baerbock getting all the attention. In retrospect, it really was a stupid decision not to insist on the Foreign Affairs ministry.
In general, hardly anyone in the FDP is happy with the traffic light coalition and its agenda so far. If the situation does not improve, there will be calls to leave it sooner rather than later.
Could Scholz cobble together a coalition if that happened or would that certainly lead to new elections?
