Overview
- Peronism’s PJ joined with La Unión Mendocina to launch the Encuentro Mendocino interbloc at the opening of the 2026 session, giving the alliance eight seats and the chamber’s first minority.
- The interbloc brings together PJ senators Pedro Serra, Mauricio Sat, Luz Llorens, Adriana Cano and Luis Novillo with LUM’s Ariel Pringles, Flavia Manoni and Marcos Quattrini, and Cano will chair the new space.
- Kirchner‑aligned senators split off to sit in a separate bloc, and Félix González and Omar Parisi formed their own two‑member bloc called Fuerza Patria.
- The Senate now has nine blocs after last year’s renewal of 19 seats, a fragmented map that leaves La Libertad Avanza positioned as a key third force in close votes.
- The ruling side kept procedural control under provisional president Martín Kerchner and set ordinary sittings for Tuesdays at 10:00, so any bill will move only if blocs cut deals across the aisle.
