This editorial, published in the Liberty Times a few days ago, was so good I was going to translate it myself. Thankfully, Perry Svensson of the Taipei Times did the hard work for me. A concluding point:
The fact that support for the DPP is slipping while support for Taiwanese independence is increasing shows that while the public wants Taiwanese independence, it is displeased with the DPP’s approach.
To extract itself from these difficulties, the DPP must either find ways to persuade the public that its approach is the right one or come up with a new approach.
It doesn’t look like the DPP will act any time soon, but the party can no longer afford to put off addressing its troubles.
