Vice President Fernando Lopez did not run for re-election and ran for the Senate instead, in which he emerged as the candidate with the most votes.

Nacionalista Eulogio Rodriguez and Lorenzo Tañada of the Citizens' Party both defended their Senate seats.

The four Liberal senators whose seats were up in this election were defeated: Camilo Osias, Geronima Pecson, Pablo Ángeles David and Vicente Madrigal.

Three winners are neophyte Nacionalista senators: Alejo Mabanag, Edmundo B. Cea and Emmanuel Pelaez.

Mariano Jesús Cuenco, who was defeated in the last election, made a comeback in the Senate, this time under the banner of the Nacionalistas.
