One-Fourth of Bangkok Voters Remain Undecided Ahead of Governor Election

Nearly one in four Bangkok voters has yet to decide whom to support in the upcoming Bangkok governor election, according to a new survey released by Thailand’s King Prajadhipok’s Institute (KPI), highlighting growing uncertainty in one of the country’s most closely watched local political contests.

The poll found that incumbent Governor Chadchart Sittipunt remains the leading candidate ahead of the June 28 election, but analysts say the large bloc of undecided voters could still significantly influence the final outcome. (Bangkok Post)

According to the KPI survey conducted between May 22 and May 25 among 1,600 eligible Bangkok voters, Chadchart received support from 31.5% of respondents. His closest challenger, Chaiwat Sathawornwichit of the People’s Party, polled at 13.1%, while Democrat Party candidate Anucha Burapachaisri received 4.9%. Almost 25% of respondents said they remained undecided. (Bangkok Post)

Incumbent Maintains Strong Lead

The latest survey reinforces Chadchart’s position as the frontrunner in the race to lead the Bangkok Metropolitan Administration for another four-year term.

Chadchart, a former transport minister who won a landslide victory in the 2022 gubernatorial election, has campaigned heavily on infrastructure upgrades, flood prevention, public transport improvements, and urban management reforms. (विकिपीडिया)

Political analysts note that his independent status continues to appeal to a broad section of Bangkok voters despite increasing competition from major political parties. Earlier surveys by Suan Dusit University also placed him significantly ahead of rival candidates. (Bangkok Post)

Opposition Parties Seek Momentum

The People’s Party has attempted to capitalize on its strong performance in Bangkok during Thailand’s recent general election, where the party swept all 33 parliamentary constituencies in the capital. (विकिपीडिया)

Chaiwat Sathawornwichit has focused his campaign on public transportation reform, anti-corruption measures, and youth-oriented urban policies aimed at younger voters.

Meanwhile, the Democrat Party is seeking to regain influence in Bangkok, once considered one of its traditional political strongholds. Former Prime Minister Abhisit Vejjajiva recently acknowledged that many traditional Democrat supporters currently favor Chadchart but insisted the party still had time to persuade undecided voters before election day.

Undecided Voters Could Determine Outcome

Political observers say the unusually large number of undecided voters may reflect broader uncertainty in Thailand’s evolving political environment following the country’s 2026 general election and constitutional reform debates. (विकिपीडिया)

Campaign strategists from multiple parties are expected to intensify outreach efforts during the final weeks before voting, particularly in middle-income urban districts where voter preferences appear more fluid.

The Bangkok governor election is regarded as politically significant because the capital remains Thailand’s economic and administrative center. The governor oversees the Bangkok Metropolitan Administration, one of the country’s most influential local government institutions. (विकिपीडिया)

The election will take place simultaneously with Bangkok Metropolitan Council elections on June 28.

Political Stakes Extend Beyond Bangkok

Analysts say the race is also being viewed as a broader test of political momentum among Thailand’s major parties following months of national political realignment.

A strong result for Chadchart could reinforce support for independent governance models in urban Thailand, while gains by party-backed candidates may strengthen national political influence ahead of future parliamentary contests.

With campaigning entering its final phase, parties are increasingly focusing on transportation, pollution, flooding, housing affordability, and public safety — issues expected to dominate voter concerns in the final weeks before polling day.
