Eduardo Frei
Preparing for the 1993 election, the Concertación held primaries in May 1993, which pitted left-wing Ricardo Lagos (PPD) against Christian-Democrat Eduardo Frei Ruiz-Tagle, (PDC), the son of former President Eduardo Frei Montalva (1911–1982, President from 1964 to 1970). Eduardo Frei won these primaries by a large majority of 63%.
