Despite the political remarriage of the two factions of the Liberal Party, the Quirinistas and Avelinistas, the Quirino administration was still far from popular.

So strong was the rejection of the Quirino administration in 1951 that even LP top honcho, Senate President Mariano Jesus Cuenco, lost his seat.

Felixberto Verano, also a Nacionalista, won the special elections held on the same day to fill the Senate seat vacated by Vice-President Fernando Lopez.

Senate President Mariano Jesús Cuenco was the sole incumbent defeated, while Carlos P. Garcia successfully defended his seat.

This also includes the result of the concurrent special election for the seat vacated by Vice President Fernando Lopez in 1949.
