My comment:
(a) Taiwanese Public Opinion Foundation 台灣民意基金會 does not have its own website (I just did an exhaustive search). So only news reports are available; especially in view of the photo in this Liberty Times report, which shows a press conference.
(b) "最後是政黨認同，在國民黨和民進黨「哪一個政黨的理念與主張和您比較接近？」的問題上，強烈民進黨人（深綠）有15.9%，溫和的民進黨人（淺綠）是33.4%，至於中性選民則為31.5%；強烈國民黨（深藍）僅3.1%，溫和國民黨（淺藍）是13.5%，2.6%不知道。"

This is what I personally consider the most important finding, that KMT supporters are a minority in Taiwan nowadays.
