The years following the People Power revolution were a period of consolidation, growth and validation of the Party's ideals and principles. Senator Jovito Salonga, by that time a three-time topnotcher at the Senate polls, was elevated to the Senate presidency in spite of there being only four other Liberals in the Upper House (Sen. Bobby Tañada, Sen. Vic Ziga, Sen. John Osmeña, and Sen. Rene Saguisag). In the Primer of the Liberal Party, Senate President Jovito Salonga, chairman emeritus, writes: "My election as senator of the Republic and my subsequent elevation to the Senate presidency signaled the coming into the fore of a united, effective Liberal Party. I was elected Senate president on June 30, 1987 despite the fact that there were only three Liberals at that time. Senator Saguisag, who was partly with PDP-Laban, subsequently signed membership papers filed with the COMELEC, manifesting his full affiliation with the Liberal Party. In the House of Representatives, 18 LP congressmen were elected under the Liberal Party."
