Background.
Soon after the reconstitution of the Commonwealth Government in 1945 Senators Manuel Roxas, Elpidio Quirino and their allies called for an early national election to choose the president and vice president of the Philippines and members of the Congress. In December 1945, the United States House Committee on Insular Affairs of the United States Congress approved the joint resolution setting the election date at not later than April 30, 1946.
Prompted by this congressional action, President Sergio Osmeña called the Philippine Congress to a three-day special session. Congress enacted Commonwealth Act No. 725, setting the election on April 23, 1946, and was approved by President Osmeña on January 5, 1946.
Results.
The election was generally peaceful and orderly except in some places where passions ran high, especially in the province of Pampanga. According to the controversial decision of the Electoral Tribunal of the House of Representatives on "Meliton Soliman vs. Luis Taruc", Pampanga "was under the terroristic clutches and control of the Hukbalahaps. So terrorized were the people of Arayat, at one time, 200 persons abandoned their homes, their work, and their food, all their belongings in a mass evacuation to the poblacion due to fear and terror."
The dominant Nacionalista Party was divided into two wings in this election. The Liberal wing was led by Senate President Manuel Roxas, while the original Nacionalista Party was headed by President Sergio Osmeña. Roxas defeated Osmeña in the concurrent presidential election, while Roxas's running mate Senator Elpidio Quirino defeated Osmeña's running mate Senator Eulogio Rodriguez.
In the Senate elections, the Liberal wing won nine seats, the original Nacionalista Party won six seats, and the Popular Front won one.
These senators from Liberal wing defended their seats: Melecio Arranz, Mariano Jesus Cuenco, and Ramon Torres. Carlos P. Garcia was the sole senator from the original Nacionalista Party to defend his seat.

Neophytes from the original Nacionalista Party are Tomas Confesor, Alejo Mabanag, Tomas Cabili, and Ramon Diokno. Newcomer Vicente Sotto was the sole candidate of the Popular Front elected.
José E. Romero of the Nacionalista was also a neophyte senator, but was unseated by the Prospero Sanidad of the Liberals, also a neophyte.
José O. Vera of the original Nacionalista Party, who last served in the Senate when it was abolished in 1935, is the sole senator to make a comeback.
