[2] The Liberal Party's campaign rally was held to proclaim the candidacies of eight senatorial bids as well as the candidate for the mayoralty race in Manila.

Ramon Bagatsing, the Liberal Party mayoralty candidate for Manila, lost his left leg and suffered a crushed right cheek bone and a shattered right arm.

[15] In interviews by The Washington Post, unnamed former CPP officials alleged that "the (Communist) party leadership planned -- and three operatives carried out -- the attack in an attempt to provoke government repression and push the country to the brink of revolution... Sison had calculated that Marcos could be provoked into cracking down on his opponents, thereby driving thousands of political activists into the underground, the former party officials said.

[20] Having blamed communists, Marcos used the bombing to justify his subsequent suspension of the writ of habeas corpus, an act which would later be seen as a prelude to the declaration of Martial Law more than a year later.

[5] Historians note that Marcos' suspension of the writ of Habeas Corpus was the event that forced many members of the moderate opposition, including figures like Edgar Jopson, to join the ranks of the radicals.

[21][22] In a setback for Marcos' ruling Nacionalista Party, the Liberals took six of the eight contested Senate seats, as well as the Manila mayoralty with then Congressman Ramon Bagatsing defeating the incumbent Antonio Villegas for the mayorship of the country's premiere city.
