New Taipei's mayoral race is heating up as the DPP and KMT camps trade jabs over campaign setup, with polls showing a tight contest.

• DPP lawmaker Lin Chu-yin accused KMT candidate Li Si-chuan of breaking a promise not to open a campaign headquarters.
• Li's camp says the criticism twists his words out of context, while word spreads that his headquarters opens in mid-September.
• DPP candidate Su Chiao-hui brushed off the fight, calling fundraising offices, headquarters and billboards normal parts of any campaign.
• Su will launch her own headquarters in early September in Banqiao and says her team is ready to lead the city.
• An online poll put Su just 2 points behind Li, close enough to be a statistical tie.

Outlook: Expect both camps to formally open headquarters in September and the race to stay close into the fall.
