Taiwan's ruling DPP has formally launched its candidate for mayor of Pingtung City, a race the party sees as hard to win.

• Liang Yu-tzu registered her run for Pingtung City mayor, backed by the DPP's local party chief and lawmaker Hsu Fu-kuei.
• Her main pitch is connecting central government money to local projects, saying the city has been stuck and needs change.
• She leans on local roots — schooled in Pingtung, daughter of a sugar refinery family — and ten years working inside politics.
• The DPP admits Pingtung City is a tough district for it, even though the party dominates the surrounding county.

Outlook: Expect the campaign to run on promises of central funding flowing into city projects, with the DPP pushing to flip a seat it has struggled to hold.
