Yup.It's pretty clear he will stay in his position as long as there are chances for Jamaica happening. Otherwise it wouldn't make sense to hold negotiations with FDP and Greens anymore.
A journalist on Dlf last week was asking why the Union was even getting ready to talk to the other parties when the will of the voters was so clearly against Jamaica. I just thought what a dumb and assumptive question that was. Just imagine the shitstorm if Ampel didn't work out and the Union wasn't ready to talk then. Laschet is the candidate so Laschet will stay on top until a coalition without the union is formed.
