I find the idea of stripping corrupt politicians of party membership an interesting one
Well, this is not a case of cleaning up the party. Ma, as corrupt as they can get, is less cleaning house than he is knocking off a competing presidential candidate. Mr. Wang has been a rival for the throne of the KMT for a number of years now, and finding an excuse to throw him out of the KMT removes an important Taiwanese-faction (as opposed to Ma’s mainland backers) contender from the next Presidential election in Taiwan. Ma is serving his 2nd term and has to step down, so there is a fight coming up for top dog.
