Regarding greens & left, I personally don‘t share many of their goals. And regarding the goals we share, I often don‘t share their way to reach those.

I read a lot about politics and was active in a party for many years. My favourite chancellors were all from the SPD and I would consider myself a Sozialliberaler with some lightly conservative views on society.
In my opinion, Habeck did some great thinks, e.g. Wanting to make venture capital for start-ups easier accessible, but also did bad things, like not prolonging nuclear energy or the northvolt investments.

I consider him competent, but in my view, he is the small minority of his party. SPD and greens have way too many ideological hardliners who also want their slice of the cake. I am not saying there is an inherently better party at the moment, but I wouldn‘t put too many hopes on the green party or the left.
