Campaign advertising significantly affects public opinion by shaping perceptions and attitudes toward candidates and issues. Strategic messaging, visuals, and emotional appeals are designed to resonate with voters, influencing their electoral preferences. Paid advertisements can either enhance a candidate's image or damage an opponent’s reputation, often through negative campaigning. Additionally, frequency and context of ads can amplify their effect, reinforcing messages more effectively over time. Overall, campaign ads play a crucial role in mobilizing support and shaping the narrative of electoral contests, directly impacting voting behavior.
