The PJ extends its power in the Buenos Aires Legislature: it will have more than half of the Senate and is close to achieving a quorum in the House of Representatives.

Axel Kicillof could celebrate that, in addition to a historic election, he will now have control of the Buenos Aires Legislature . The legislative renewal left Fuerza Patria with 40 deputies in its bloc (just 6 short of a quorum) and 24 senators, which exceeds half plus one of the 46-seat body.

This is the result of having obtained 34 seats in these elections (21 in the House of Representatives; 13 in the Senate) after having achieved first place in six of the eight sections into which the Province is divided.

But the potential isn't due to the fact that these overall numbers can be modified with the final count or because a section registers a last-minute change. The proper management of the provincial parliament depends on the willingness of the Massa faction and La Cámpora—the governor's allies—to support initiatives emerging from the Executive Branch.

It's happened several times in recent months. The Governor's proposals were blocked by internal controversies rather than opposition resistance. This happened with the ill-fated 2025 Budget debate; the disputes over the postponement of the PASO (Primary Elections) were intense and drawn-out, and the debate over the electoral split that led to this election date, which was resolved this Sunday, proved to be almost a battle without bullets.

To achieve progress on the Governor's proposals at the 8th and 53rd Streets (where Parliament sits), not only does it require a solid coalition of its own, but it also requires alignment with the leaders of the provincial governing bodies.

After the ballot box was overturned, the La Libertad Avanza (LLA) alliance has 18 new representatives and 8 provincial senators . This is far more than it had previously proposed and far above its current tally. On December 10, five purple-clad legislators will leave their seats, out of a 12-member bench. Therefore, starting with the new swearing-in, 25 representatives will be consolidated in this bloc. It will be the second largest in the chamber.

We'll have to observe the behavior of the two who joined as part of the agreement with the PRO. And we'll have to determine how the five "yellow" candidates who still have mandates until 2027 perform.

Taken as a whole, the Libertarian Front and the PRO were at risk of 13 seats (8 for the PRO and 5 for the LLA), but with tonight's results, they gained 21 seats. This could be interpreted as a net gain of 8 seats .

We'll have to wait and see how time and sessions go by to determine whether they maintain a sense of coexistence and reach agreements for debates or whether they continue to operate as separate blocs.

The growing polarization of the September 7 election nearly pulverized other parties that had attempted to intervene . "Hechos," the party promoted by the Santiago and Manuel Passaglia brothers—based in the San Nicolás district—will debut in the legislature with three seats; "Somos Buenos Aires," the radical-based alliance that presented lists in seven of the eight sections, only managed to secure two seats (in the fourth section), and the left was able to retain the two seats that came from the Third.

In terms of a party, the UCR was one of the hardest hit . The UCR-Cambio Federal bloc, led by National Senator Maximiliano Abad, was at risk of 5 of its 9 seats and failed to retain any . Meanwhile, Somos Buenos Aires, aligned with Facundo Manes, was defending 5 of its 6 seats and managed to retain only 2.

The ruling party, currently known as "Unión por la Patria," is made up of 21 senators: it was up for grabs with 10 and secured 13 new seats. With these 24 seats, it doesn't need allies to hold sessions and achieves its own quorum. It's worth noting: allies must also be found among its own members, because several of those joining report to Cristina Kirchner and La Cámpora.

The PRO-La Libertad Avanza alliance won 8 senators in this election. They were putting 5 at stake (4 from PRO and 1 from LLA), thus also expanding their representation, although the same logic applies as in the House of Representatives: will the new and previous candidates form a single LLA Alliance bloc, or will each follow their own path? The discontent that emerged immediately after the numbers were released predicted that the agreement would be too fragile, and the recriminations were already beginning. Threats of segmentation and of holding onto their own territories to avoid further losing power.
