ROXAS AT ROXAS, ISABELA: Liberal Party vice presidential race front-runner Senator Mar Roxas is mobbed by supporters in Roxas, Isabela during a recent campaign sortie. Forty-seven groups representing close to half a million farmers nationwide have endorsed the candidacy for Vice-President of Roxas and his presidential candidate, Sen. Benigno S. Aquino, because they are confident an Aquino-Roxas administration would ensure the full and sincere implementation of the agrarian reform program.
