A new poll puts the DPP's Su Chiao-hui ahead of the KMT's Lee Si-chuan in the New Taipei mayoral race, a positive sign for the DPP in a city the KMT has long held.

• Su leads Lee by roughly 6 points, with support in the high 30s against low 30s.
• Su's campaign says the result matches the trend it sees in other polls and points to growing grassroots support.
• The survey polled adults across New Taipei by phone in late August, with a margin of error of about 3 points.
• New Taipei is Taiwan's most populous city, making it one of the marquee contests of the nine-in-one local elections.

Outlook: With about three months until the vote, expect more polls and a sharper KMT counter-push as the race tightens.
