Lien lost his last chance and does not want to accept it. He's trying to gamble with the future of 苦主国民党. Look at 小马哥's response. Sigh, old KMT is gone with those old guys. Whatever others think about this election, around 50% support CSB, compared to only 39% in 2000 election. These 2 numbers pretty much explain a lot.
CSB with his DPP may not be an ideal leader for Taiwan, but a lot of Taiwanese would rather pick him than KMT because they couldn't forget what KMT did for its almost 50 years' control.
Don't blame DPP and CSB. Even if Lien is elected, he would not choose to unite with PRC. This is the reality in Taiwan. For KMT fans, expect a new KMT, the old is gone.
