Slogans
The longtime slogan of the People's Democratic Party has been "Power to the people".

The PDP is against same-sex relations, and favors social conservatism on moral and religious grounds. In 2007, the PDP-dominated National Assembly sponsored a bill to outlaw homosexual relations, making it punishable by law for up to 14 years in prison. The party is a moderate advocate of state-autonomy and religious freedom for the Nigerian states. In the year 2000 the introduction of Islamic law in some states in Northern Nigeria triggered sectarian violence in Kaduna and Abia states. The PDP-led federal government refused to bow to pressure from the southern, predominantly Christian states to repeal the law, and instead opted for a compromise where Islamic law would only apply to Muslims. Tunde Ayeni, chairman of the PDP fundraising event in December 2014 who donated N2 billion was involved in the mismanagement of bank's funds.
