Propaganda affects public opinion by shaping perceptions, beliefs, and attitudes toward specific political issues, figures, or policies. By presenting information in a biased or manipulative manner, propaganda can influence behaviors, often stirring emotions to elicit specific responses from audiences. It can reinforce existing beliefs or create new narratives, affecting voter behavior and public sentiment. This manipulation of information complicates the quest for an informed electorate, as individuals may struggle to discern truth from misinformation, ultimately threatening democratic processes.
