Daily Woody | Jun 04, 2026 — Korea's ruling party wins 12 of 16 regions, loses Seoul
South Korea's June 3 local elections, the first nationwide vote since President Lee Jae-myung took office a year ago, concluded Thursday, with the ruling Democratic Party winning 12 of 16 metropolitan-chief posts. The conservative People Power Party held just four — Seoul, Daegu, and the two Gyeongsang provinces. In the marquee Seoul race, Oh Se-hoon overturned a long deficit after 13 hours of counting to secure a record fifth term. In Gyeonggi, Choo Mi-ae became the first woman to head a Korean metropolitan government. Turnout reached about 61%, the highest for a local election since 1995.
The seat count, 12 to 4, reads like a landslide. The margins do not. Seoul flipped only at the very end; South Gyeongsang stayed a coin-flip past midnight. Set against the Democratic Party's 2018 rout, this win was wide but thin. The memory of Yoon Suk-yeol's martial law eroded the conservative base outside the southeast — yet the right held the capital's symbol and its heartland.
The Democratic Party now adds regional power to its hold on the legislature and the presidency, which points investors toward policy continuity rather than gridlock. But two footholds stay with the opposition — City Hall and the southeast. Oh Se-hoon as a five-term mayor, and Han Dong-hoon, revived in Busan, become the twin pillars of a conservative rebuild well before the 2027 presidential race.
South Korea elects 16 metropolitan-level leaders — mayors of major cities and provincial governors, down from 17 after Gwangju and South Jeolla merged this year. This was the first nationwide test since December 2024, when then-president Yoon Suk-yeol briefly declared martial law, was impeached, and Lee Jae-myung won a snap election. First-year ruling parties usually win these "honeymoon" votes; the twist this time was the opposition holding Seoul.

Running as an independent, former PPP leader Han Dong-hoon won the Busan Buk-gu A by-election with 42.99%, edging Democratic candidate Ha Jung-woo by 1,425 votes after trailing through three-quarters of the count. A split conservative vote nearly cost him the seat. Han cast the win as a mandate to rebuild the conservative camp — and his clearest step back onto the national stage.
Several polling stations in southern Seoul ran out of ballots on the afternoon of June 3, leaving voters queuing. The National Election Commission's secretary-general apologized publicly that evening and let waiting voters cast ballots after the official close. The PPP demanded a halt to counting and a re-vote and visited the Seoul election office to protest; the Democratic Party dismissed the claim.
A US-brokered ceasefire track with Iran wobbled again — and oil, a direct input to Korea's import-driven economy, swung with it.
Iran's state-linked Tasnim outlet said on June 1 it would halt talks with Washington and move to fully close the Strait of Hormuz, citing Israel's offensive against Hezbollah in Lebanon. Oil jumped more than 7%. President Trump then said a deal remained reachable within a week, and Hezbollah reportedly accepted a US ceasefire proposal — leaving the track alive but fragile.
This negotiation hinges not on Iran's nuclear program but on Lebanon. Tehran tied its one real lever — Hormuz — to a ceasefire on soil that is not its own. Brandishing the blockade as a bargaining chip serves Iran better than actually closing the strait.
For Korea this is not distant news. It imports most of its crude and LNG through Hormuz, where traffic has fallen to about 5% of normal since the war began in February. Every stumble in the talks moves oil roughly 7%, and Korea's inflation and trade balance move with it.

At Asia's premier security summit, Japan pushed back hard on China's "militarism" charge — a gauge of Northeast Asia's rising defense temperature.
At the Shangri-La Dialogue in Singapore on May 31, Japanese Defense Minister Shinjiro Koizumi rejected Chinese accusations of "new militarism," saying it was strange for a nuclear-armed power to apply the label to a country that has no such weapons. He did not name China. The remarks followed PM Takaichi Sanae's expanded "free and open Indo-Pacific" plan and wider defense-equipment cooperation. China's defense minister skipped the summit for a second straight year.

The shape of November's US midterms began to firm up in early-June primaries.
Six states, including Iowa, held primaries on June 2, shaping the midterm field. Iowa's Senate race is now set between Republican Rep. Ashley Hinson and Democratic state Rep. Josh Turek. The Trump administration's record and the war with Iran are emerging as the central themes of the cycle.

Voters picked progressive school superintendents almost everywhere — except, tellingly, where they also picked a conservative mayor.
Progressive-leaning candidates won around 11 of 16 superintendent races, ending the 9-8 split of 2022. In Seoul, incumbent Jung Keun-sik won re-election and pledged to rebuild a school community of reconciliation. Conservatives held only their incumbent strongholds — Daegu, North Gyeongsang, and North Chungcheong.
Seoul is the tell. Voters there chose conservative Oh Se-hoon for mayor and progressive Jung Keun-sik for schools — splitting administration from education on the same ballot. Superintendent races carry no party labels, and this year Seoul showed they do not always track the top of the ticket.
The broader current still favors progressive educators, who will revive pledges on public-school funding and closing achievement gaps. But the learning losses and eroded teacher authority left by the pandemic do not yield to slogans. What the winners must prove now is change in the classroom, not on the banner.

In the Pyeongtaek-B re-election, the PPP's Yoo Eui-dong won a three-way race decided after midnight, edging the Democratic and Rebuilding Korea candidates by about a point each. Rebuilding Korea leader Cho Kuk, seeking a return to parliament, conceded and called the outcome his own failure. Unlike Han Dong-hoon in Busan, Cho's comeback will have to wait.
The Democratic Party won 17 of Seoul's 25 ward-mayor posts, reversing a loss of the same size four years ago. The PPP held the affluent Gangnam-area districts. Even as conservatives kept City Hall, the boroughs beneath it swung to the Democrats — a split verdict inside a single city.

The Office of the US Trade Representative on June 2 proposed tariffs of 10-12.5% on 60 economies it says failed to block goods made with forced labor. Korea, lacking a dedicated import ban, was grouped at 12.5% alongside China, Japan, and Britain. After the Supreme Court struck down reciprocal tariffs in February, the administration is routing the new levies through Section 301. A comment period and a July hearing precede a final decision. Seoul's presidential office said it would protect the balance of the existing Korea-US tariff deal.

AI data-center demand has pushed DRAM and NAND prices to as much as seven times their level a year ago. Korea's chip exports to the US rose 651% last month. On the strength of that, the KOSPI closed at a record 8,788 on June 1, up nearly 4%, with market capitalization topping 7,000 trillion won for the first time (per MBC). Analysts warn that boom-time capacity tends to return later as a glut.

[Gukje News] A brush fire near the election commission compound in Gwacheon broke out during counting on June 3 but was knocked down in 12 minutes, with no effect on the tally.
Thursday brings broken cloud over central regions and scattered showers nationwide except Jeju through the night, with a risk of gusts, thunder, lightning, and hail. Friday turns clearer from the morning after early rain in central and southwestern areas.
| Date | Conditions | Notes | Low / High (℃) |
|---|---|---|---|
| Thu Jun 4 | Cloudy, evening showers | Gusts, thunder, hail possible | 17~23 / 21~30 |
| Fri Jun 5 | Cloudy, clearing AM | Early rain, central & southwest | 15~20 / 23~31 |
| Sat Jun 6 | Mostly clear (clouds late) | South clears in afternoon | 11~18 / 24~29 |

⚠ Note — Heavy downpours with gusts, thunder, lightning, and hail are possible nationwide (except Jeju) through Thursday night; some areas may exceed 80mm. Take care outdoors.
The numbers said 12 to 4. The margins said otherwise. Seoul turned over to Oh Se-hoon only after 13 hours of counting; South Gyeongsang split past midnight. The Democratic Party won broadly, but in many places narrowly.
On the same day, ballots ran out in central Seoul. The election chief bowed in apology; the opposition called for a re-vote. Triumph and a crack in the machinery sat side by side.
Voters handed the ruling party the provinces, yet left it the capital and the southeast to reckon with. They kept an ember of restraint alight. The real test of this victory is how the winners read those thin margins.
