Taiwan's Pingtung county race is shaping up as a rematch that favors the ruling DPP incumbent, though a hospital fire scandal and flood anger are reshuffling both sides.

• Chou Chun-mi won last time by only about 11,000 votes and now runs with the advantages of holding office.
• Su Ching-chuan is running again for the KMT, but a fire at the hospital he founded killed nine people and left him facing court proceedings and doubts from his own side.
• Heavy rain and flooding along the coast have revived his campaign, and he is attacking the county government over health care, schools, and aggressive speed-camera fines.
• Chou is leaning on her record, including bringing tech companies into the county, in a district where the DPP has governed for 28 years.
• The bigger threat to her is internal DPP friction that has been papered over rather than settled.

Outlook: Chou starts as the favorite, but flood anger and green-camp infighting could narrow the race again.
