Senator Eulogio A. Rodriguez, Sr. "Amang", party head of the Nacionalista Party, tasked Senators Fernando H. Lopez and Gil J. Puyat to convince Angeles David to join the Nacionalista's "sure-win" Senatorial Ticket. David Angeles refused in order to preserve the two-party system; which he believed to be a safeguard against dictatorial tendencies. Instead of campaigning for re-election, he attended the Interparliamentary Union (IPU) Conference in Berne, Switzerland.
