Isn’t it the stronghold of DPP and Taiwanese mobs?

[Tainan]

DPP does have a presence in K-Town, but they are the 2nd largest political party so they are, really, everywhere.
As to "mobs", organized crime is extremely strong here - especially in the construction trades.
But unless you are involved with them in some way, you would not be aware of their existence. But they are very powerful on the upper levels of gov't.
Taoyuan and Taichung are two of the more notable mob-cities - gov't and influence peddling.
Well, and Taipei, of course. That is where the gov't headquarters are located.
