At first, UNIDO supported Senator Salvador Laurel of Batangas as its standard bearer, but business tycoon Chino Roces was not convinced that Laurel or Jovito Salonga could defeat Marcos in the polls.

Roces initiated the Cory Aquino for President Movement (CAPM) to gather one million signatures in one week to urge Aquino to run as president, convincing Aquino to do so.
