Taiwan discretization - 1.4:1 not (3:1)
The voting result in Taiwan is KMT 53.5%:DPP 38.17%.
This is approximately 1.4:1 or 7:5. A mighty accomplishment for KMT. But it is not as absolute as the magic numbers 81:27 (i.e. 3:1) in terms of seats.
DPP only has itself to blame for such a strategic mistake, and incompetence in governing. Chen stepped down not because he has failed the voters with the corruption and governing fiasco, but because he has agreed to the rule of game that would magnify 7:5 into 3:1. As to how this magnification works, I will refer you to twofish, a great blog unfortunately also blocked by our GFW nanny.
