As the Taipei mayoral race heats up, the question of Chiang Wan-an's bloodline has been dug up again — an irritant the KMT camp cannot shake off.

• Kuo Yi-hsi, son of the late general Kuo Li-po, has softened his stance, saying that as long as Chiang Wan-an is willing, he has no objection to a DNA test.
• Chiang Wan-an responded with resignation, asking "why does every election have to involve a discussion of DNA," but did not give a direct yes.
• Chiang Wan-an's eldest son receiving an international exchange student subsidy has also drawn criticism; the Agency Against Corruption stressed that related parties applying for subsidies are required to disclose their identity truthfully in the first place.
• With the KMT–TPP alliance in Hsinchu County having collapsed, the TPP has issued an expulsion order, and KMT candidate Hsu Hsin-ying faces a tight race — she could win Zhubei City but lose the county magistracy.
• Chen Shih-chung attacked Chiang Wan-an over his appearance, prompting KMT councillors to hit back: "Is the conclusion after four years of reflection that you lost on looks?"

Outlook: With the nine-in-one elections approaching, the doubts over Chiang Wan-an's parentage and the rift between the KMT and the TPP are expected to be amplified repeatedly, becoming the main lines of attack and defence in the two major battlegrounds of Taipei and Hsinchu.
