The King Prajadhipok Institute revealed survey results on political bases regarding the election of the governor and the trend in councilor (S.K.) elections before the final round. It found that "Chadchart" leads across party bases, while in the councilor race, the "Prachachon" party leads.
On 19 June 2026, the King Prajadhipok Institute announced the results of its 25th KPI Poll conducted at the center, surveying 1,600 citizens aged 18 and over across Bangkok districts from 4-7 June 2026. Key findings from the survey are as follows:
1. If you are a Bangkok resident, to what extent would you study the policies of the governor candidates you are interested in or likely to choose? (Survey conducted by x Line Today)
• 46.6% stated they would "study thoroughly, both main policies and feasibility."
• 30.1% said they would "study partially or through media/social media," 12.2% "study moderately/to know key policies," 6.6% "might not study policies seriously," and 4.5% were unsure or had no opinion.
➡ Nearly half pay attention to candidates' policies, reflecting that policies are increasingly influencing voting decisions. However, some interest is limited to partial awareness and following, posing a challenge for candidates and parties to improve policy communication so elections are based more on informed reasons rather than just popularity or candidate image.
2. “Chadchart” leads across party bases; “Dr. Joe” stands out among Prachachon supporters; “Anucha” leads within the Democrat base.
Considering party support from the 8 February 2026 district MP elections, "Chadchart Sitthiphan" tends to lead in several bases: Prachachon party 45.4%, Pheu Thai 42.1%, Bhumjaithai 54.4%, other parties 52.3%, and those who don’t recall/did not vote/did not want to answer at 30.8%.
• Meanwhile, within the Prachachon party base, "Dr. Joe Chaiwat Sathaworawijit" received 30.6% as the runner-up, and in the Democrat base, "Anucha Burapachaisri" leads at 31.1%, followed by other candidates at 25.8% and "Chadchart" at 22.7%.
This shows that the Bangkok governor race still clearly weighs the individual candidate more than party affiliation. Chadchart can attract votes across multiple party bases, but Prachachon and Democrat bases maintain their distinct directions, making the competition not just a measure of overall popularity but also a contest for vote bases with different behaviors in each political group.
3. When choosing councilors, voters focus more on "policies" than "party."
• 34.9% stated they choose councilors based mostly on the "policies proposed."
• Next, 21.9% consider party/group affiliation, 17.9% past performance, 11.6% the individual candidate/image, and 13.7% did not respond.
This reflects that councilors are not viewed merely as party political representatives but are expected to understand local issues and offer tangible solutions to city and district problems. However, "party and political base" still significantly influence decisions. Candidates must compete through policies, track records, and local credibility, not just rely on party momentum or governor popularity.
4. In the councilor race, Prachachon leads, but independent candidates and undecided voters remain significant variables; over half remain open-minded.
If the councilor election were held today, candidates from the Prachachon party would likely lead with 27.7%, followed by independents at 18.5%, undecided voters at 17.7%, Democrat party candidates at 11.5%, and Pheu Thai party candidates at 10.6%. Other groups scored lower.
When parties/groups/individuals propose policies that resonate, 38.3% say they are still unsure but open to considering, 32.8% will stick to their current choice, 15.4% are highly likely to change their mind, and 13.5% did not respond.
The councilor race remains "open." Although Prachachon leads, independent candidates and undecided voters have substantial support, reflecting that proximity to the area, feasible policies, and candidate credibility remain very influential. Candidates must show how they represent the area, push local issues, and oversee Bangkok’s administration, rather than relying solely on party or broader political trends.
Summary from the 25th KPI Poll
The Bangkok election before the final round remains highly dynamic, especially in the councilor race where voters remain open and can change their minds if presented with better proposals. This survey reflects that the final phase of the Bangkok election will be decided by the ability to convert popularity into actual votes and communicate policies that concretely address city and local issues, rather than relying solely on "party momentum or candidate image."
