Election Day
These elections were less fraudulent than the congressional elections, as the ruling party had limited capacity for wholesale fraud. The vigilance of the electorate, media, and the opposition safeguarded the exercise from manipulation. Elections in "hot spots" were postponed by COMELEC to prevent possible violent encounters between rivals. Most of the candidates endorsed by Cory Aquino won the support of the majority of the electorate.
