Oh my word.
Do you understand that there is an electoral system called PROPORTIONAL REPRESENTATION and another called FIRST PAST THE POST??
If you bothered to take a look at the election I sourced, it had the CDU/CSU winning a seat percentage of 77%, with like 36% of the votes. You think that's PROPORTIONAL?
Also another party who got 7% of the votes and 0% of the seats. You think that's PROPORTIONAL???
I'm not suggesting anything. I'm showing you what PROPORTIONAL REPRESENTATION IS.
And if I were suggesting a different system, you saying "but we don't have that" is like me saying "Do you want chicken for dinner?" and you saying "But I have beef", as if you couldn't choose chicken because you have beef in the fridge.
