This article [CN] shows everything that's wrong with the DPP message on cross-strait relations. President Ma Ying-jeou recently made a big deal about that DPP policy in an interview with media, and there he rhetorically asked Tsai Ying-wen if the DPP accepted the 92 consensus.
Tsai responded by saying how the 92 consensus doesn't exist; just ask President Lee Teng-hui or Koo Chen-fu, Lee's President of the Straits Exchange Foundation and the man who would have been in charge of any talks held under a "'92 consensus."
But Tsai completely misses the larger point, namely, that the DPP cannot accept the '92 consensus because of its definition. The '92 consensus is defined as "Taiwan and China both belong to One China," and the KMT government likes to add a flourish: "The Republic of China is that One China."
No matter which definition you use, it does not reflect reality and it is not at all reasonable. Nor does it reflect the average Taiwanese person's opinion.
If the DPP could remember that not everyone watches their political talk shows every day, maybe they'd realize how few people could tell you off hand what the '92 consensus is. And it's the act of getting that definition out which will win people over to the DPP's side.
