Buenos Aires Poll Shows Jorge Macri Leading 2027 Race

The numbers also show a more complicated picture beneath that lead. Bullrich has the best positive image in the field at 49.3%, well above Macri’s 32.5%, but that approval does not automatically turn into votes for City Hall. Macri’s image is almost evenly split at 32.5% positive, 33.6% regular and 33.9% negative, suggesting a politician with a stable but polarized base rather than broad enthusiasm.

The political significance is bigger than one poll. In a city where voters are often sensitive to local management and coalition labels, 41% of respondents said Macri would “stay in the house and keep it running” if the PRO-LLA marriage breaks down because of a third party. Another 26.5% said he would seek forgiveness and return, while 20.9% said he would move in with more moderate allies.

That interpretation gives Macri a valuable narrative advantage: he is being framed not just as a candidate, but as the person who already owns the machine. The idea is reinforced by the city’s appetite for a separate local election, with 72.7% preferring that Buenos Aires vote on its own date rather than alongside the national contest.

For investors, the poll matters because Buenos Aires often serves as a proxy for Argentina’s broader policy direction and the durability of Milei’s political coalition. La Libertad Avanza leads the party-level vote at 29.9%, narrowly ahead of the PRO at 28.3%, which points to an unstable right-wing balance rather than a clean handoff.

If the alliance holds, the poll suggests the main fight will be over who heads the ticket. If it breaks, Macri appears to have enough local identity to remain competitive, while Milei’s camp still has to prove it can convert national momentum into city-level control.

For now, the story in CABA is not just that Macri leads. It is that voters appear willing to let him keep the keys even if the broader political family splits.
