 Seoul’s political mood is hard to read. Poll numbers are moving, but many voters are holding back. The central dynamic in the race is this: public sentiment appears to be shifting, but many people still hesitate to vote.
 
 Recent published polling trends still show a gap, with candidate Jeong Won-o ahead and candidate Oh Se-hoon closing in. But reading the race only through charts is risky. The key is momentum. Oh’s gradual rise matters because small shifts can become the start of a turnaround.
 
 Against that backdrop, Jeong’s campaign was hit by a controversy over a promotional post citing a poll. The material was posted without required disclosure items such as the polling firm and survey period, then deleted at what critics called “the speed of light.” The episode left a political impression beyond a simple mistake. A front-runner needs steadiness, not haste, and the incident suggested a campaign in a rush. With similar disputes said to have occurred repeatedly, Jeong’s camp may struggle to avoid criticism of poor oversight.
 
 In politics, impatience can be costly. The more a candidate leads, the more composure voters expect. When a small error hardens into doubts about why a campaign is rushing, the contest can shift from numbers to psychology. For Jeong, the immediate need is tighter management, not more messaging.
 
 For Oh’s side, the moment creates an opening. Challengers start at a disadvantage, but they can benefit first when the race becomes unstable. If the opponent repeats mistakes, momentum can move without direct attacks. In that sense, elections can reward the side that holds steady when the other side wobbles.
 
 The biggest variable, however, may be undecided voters. In conversations with residents, a pattern keeps emerging: distrust of politics, fatigue with the two major parties, and signs of weakening willingness to vote.
 
 One resident described themselves as “undecided” while sharply criticizing certain political behavior. Yet when asked whether they would vote, the answer became uncertain. That reflects a slice of Seoul’s mood. This type of distrust-driven undecided voter could be decisive. They do not move easily, but when they do, they can shift the race. The risk is if they do not move at all: turnout falls, and the side with stronger organization gains an advantage. It is a democratic paradox — anger without action — and the article describes it as a warning sign.
 
 Intense political clashes and disputes over prosecutors and special prosecutors are also adding to fatigue rather than energizing voters, the article says. Instead of generating momentum through conflict, politics is widening cynicism. A typical result in such moments is a low-turnout election.
 
 The race, then, is not only about who leads in support. It is also about who can get more voters to the polls. A front-runner can stumble through complacency, and a challenger can flip the contest by seizing an opening. Meanwhile, undecided voters may delay their decision until the end. For now, the article concludes, sentiment in Seoul may be moving, but whether it turns into votes remains unclear — and the gap could close quickly depending on who bridges it first.
