The main contenders in this election were Manuel L. Quezon, the incumbent president of the Commonwealth of the Philippines, under the ruling Nacionalista Party, with incumbent Vice President Sergio Osmeña as his running mate; and Senator Juan Sumulong of the Popular Front-Sumulong Wing (also called Pagkakaisa ng Bayan), with Dr. Emilio M. Javier as his vice presidential candidate. Other presidential-vice presidential tandems include Pedro Abad Santos and Pilar V. Aglipay of the Popular Front-Abad Santos Wing; Celerino Tiongco I of the Partido Ganap de Filipinas, with Aglipay as his running mate; and Hilario C. Moncado of the Partido Modernista and Partido Liberal de Filipinas, with former president Emilio Aguinaldo as his running mate. Abad Santos and Aguinaldo later withdrew their candidacies for president and vice president, respectively. Other candidates include Ernesto Tupas Belleza, Hermogenes Dumpit and Veronica Miciano, independent presidential candidates, and Pedro Yabut, an independent running for vice president.
Quezon and Osmeña performed better than their 1935 poll performance, winning all the provinces. Their feat as a tandem is unmatched to date.[2] The only place that Sumulong won is his hometown, Antipolo in the province of Rizal, where he won by a slim margin over Quezon.
