Why does it have to be 50-50 in Germany's Bundestag [duplicate]
In Germany's Bundestag, 299 seats are for proportional representation and the other 299 are for regional representation in a first-past-the-post system. Is it just a coincidence that the seats are split right down the middle?
According to a book that I am reading, this is the only way by which the German system can work.
On the other hand, in Japan's parliamentary system, the number of electorate MPs does not have to be the same as that of list MPs.
The author then went on to argue that because the Bundestag seats are evenly divided between electorate MPs and list MPs, the German system is better for small parties. On the contrary, the Japanese system is bad for small parties because the seats are not evenly distributed among electorate MPs and list MPs. But all of this just doesn't make any sense to me, and the book doesn't provide much explanation for the assertions.
One last thing: I am sorry that I might not be able to cite the book. It's written in Mandarin.
