A choice between two visions mapped onto Peru's deep inequalities
In the weeks before Peru's June 6 presidential runoff, a Datum poll of 1,205 citizens revealed a country divided not merely between two candidates, but between two Perus — one urban and prosperous, the other rural and long overlooked. Pedro Castillo held a 15-point national lead over Keiko Fujimori, yet a third of the electorate remained uncommitted, reminding observers that in a nation of deep inequalities, the final word had not yet been spoken.
- Castillo's 41% to Fujimori's 26% margin signals a powerful surge from Peru's rural and working-class majority, making him the early favorite with over a month to go.
- A full third of voters — 18% undecided and 15% planning blank or spoiled ballots — keeps the outcome genuinely open and both campaigns on edge.
- The geographic fault line is sharp: Castillo dominates the north, center, south, and east, while Fujimori holds Lima and the wealthiest economic sectors almost exclusively.
- The class divide mirrors the map — Fujimori leads among sectors A and B, while Castillo commands overwhelming support in the C, D, and E brackets that make up most of the country.
- With campaigns still active and perceptions still shifting, the question is whether Castillo's broad coalition outside Lima can hold against whatever ground Fujimori may yet gain in the capital and among undecided voters.
Peru's presidential runoff was crystallizing into something more than a political contest — it was a referendum on the country's deep internal divisions. Datum's first survey of the Castillo-Fujimori matchup, drawn from 1,205 Peruvians nationwide, showed the rural schoolteacher and union leader holding a commanding 15-point lead: 41 percent to Fujimori's 26 percent.
Yet the full picture was more unsettled. Nearly one in five respondents remained undecided, and another 15 percent planned to cast blank or spoiled ballots — a protest tradition in Peruvian elections. Together, these voters amounted to a third of the electorate still in motion.
The geographic breakdown laid bare the fractures in Peruvian society. Castillo led decisively across the northern, central, southern, and eastern regions — areas that are poorer, more rural, and historically distant from the country's centers of power. Fujimori's support was concentrated in Lima, the seat of wealth and institutional influence. The class dimension reinforced this divide: Fujimori led among the wealthiest sectors, while Castillo dominated among working and lower-income Peruvians.
With election day still more than a month away, the undecided vote left room for the race to shift. But Datum's snapshot made clear that Castillo entered the final stretch as the favorite — carried by a broad coalition of Peruvians outside the capital who saw in him something the country's political establishment had long failed to offer them.
Peru's presidential runoff was shaping up as a stark geographic and economic divide. With just over a month until voters would return to the polls on June 6, the country faced a binary choice: Pedro Castillo or Keiko Fujimori. Datum, one of the country's major polling firms, released its first survey of the matchup, and the numbers suggested momentum was building in one direction.
The poll, which contacted 1,205 Peruvians across the country, showed Castillo commanding a substantial lead. He registered at 41 percent support, while Fujimori trailed at 26 percent—a gap of 15 points that was difficult to ignore. But the picture was more complicated than a simple head-to-head. Nearly one in five respondents, 18 percent, remained undecided. Another 15 percent said they would cast blank or spoiled ballots, a form of protest vote that had become a recurring feature of Peruvian elections. Together, these groups represented a third of the electorate still in play.
The geography of support revealed the fractures running through the country. Castillo's strength lay everywhere except the capital. He led decisively in the northern regions, the central highlands, the southern territories, and the eastern jungle. Fujimori's base was concentrated in Lima, where she held the advantage. This was not incidental—Lima represented wealth, urban sophistication, and institutional power. The regions Castillo dominated were rural, poorer, and historically marginalized from the country's political and economic center.
The class dimension was equally stark. When Datum broke down support by economic sector, the pattern crystallized further. Fujimori led among the wealthiest Peruvians, those classified in sectors A and B. Castillo dominated among the working and lower-middle classes in sectors C, D, and E. This was not a close contest in those lower-income brackets. The runoff was crystallizing into something the country had not fully reckoned with: a choice between two visions that mapped almost perfectly onto Peru's deep inequalities.
With more than a month remaining before election day, the undecided voters and the blank-ballot contingent represented genuine uncertainty. Campaigns could still shift perceptions, scandals could emerge, and turnout patterns could change the math. But Datum's snapshot suggested that if the election were held immediately, Castillo would enter the runoff as the clear favorite, carrying the support of the majority of Peruvians outside Lima and the upper-income brackets. The question was whether that coalition would hold, and whether the substantial portion of voters still making up their minds would break toward him or toward Fujimori.

Why does this poll matter right now, in April, when the election isn't until June?
Because it's the first real measurement of how Peruvians see a choice between these two specific candidates. The primary was chaotic—there were 18 candidates. Now it's binary, and people are actually thinking about it.
The 18 percent undecided seems high. That's almost a fifth of voters.
It is. But remember, this is the first poll of the runoff. People are still getting their bearings. What's more telling is where those undecided voters live and how much money they make—we don't know yet.
The blank vote number is striking. Fifteen percent planning to spoil their ballot?
It's a form of rejection. It says something about how Peruvians feel about both options, or about the system itself. That's not a small thing.
So Castillo wins Lima and loses everywhere else?
Exactly backwards. Fujimori wins Lima. Castillo wins the rest of the country. That's the story—the capital versus the regions.
And the money split—Castillo wins the poor, Fujimori wins the rich?
Yes. It's almost a perfect mirror. Which means this isn't really about personality or individual scandals anymore. It's about class.
Can Fujimori close a 15-point gap in a month?
Theoretically, yes. But she'd need to move voters in the regions and lower-income sectors. That's not her base. She'd have to convince people to vote against their own economic interests, or convince them she represents something different than she has before.
