A political action committee (PAC) is an organization that raises and spends money to elect or defeat candidates, while a Super PAC can spend unlimited funds on independent political advocacy but cannot contribute directly to candidates or parties. PACs typically represent specific interests, such as business sectors or labor unions, and are subject to contribution limits. Super PACs, however, emerged from legal rulings allowing significant financial contributions from individuals and corporations, which raises concerns about the influence of money in politics and the potential distortion of democratic representation.
