Both territories had been adverse to Peronism since 2005, when the Frente para la Victoria label had triumphed. In the Fourth Section, which borders on La Pampa and contains 19 municipalities, Peronism also put paid to the ambitions of Somos Buenos Aires, the UCR-led alliance with ambitions of presenting itself as an alternative to polarisation. The district consists of the municipalities of Alberti, Bragado, Carlos Casares, Carlos Tejedor, Chacabuco, Chivilcoy, Florentino Ameghino, General Arenales, General Pinto, General Viamonte, General Villegas, Hipólito Yrigoyen, Junín, Leandro N. Alem, Lincoln, Nueve de Julio, Pehuajó, Rivadavia and Trenque Lauquen. There seven Senate seats were at stakes: Fuerza Patria took three, LLA two and Somos Buenos Aires the other two. The LLA totalled 36.63 percent of the votes with Fuerza Patria headed by Juan Ariel Archanco finishing on top with 43.91 percent.
