Taiwan will hold its biggest and most complicated local election ever on November 28, a huge logistical test for the election commission and a high-stakes moment for the ruling and opposition parties.

• About 19.65 million voters will pick 11,051 local officials in one day of voting.
• The scale is enormous: nearly 9,000 voting districts, more than 8,000 different ballot types, and over 18,000 polling stations.
• Roughly 250,000 staff will run the vote — over 300,000 if three referendums proposed by the opposition KMT and TPP are added.
• The election commission set up a task force in August to fight AI deepfake videos, fake news, cyberattacks, and foreign interference, working with prosecutors and national security agencies.
• If the referendums go ahead, counting is expected to run into the early hours of the next morning.

Outlook: The commission reviews the three referendum proposals on August 28, and that decision will shape both the ballot and how long the count takes.
