Campaign advertisements impact voter decision-making by shaping perceptions of candidates and influencing public opinion. Through targeted messaging, these ads can highlight key issues, personal qualities, and policy positions that resonate with voters. Effective advertisements can sway undecided voters or reinforce existing preferences, ultimately affecting election outcomes. The emotional appeal and imagery used in ads play a crucial role in capturing attention and fostering engagement. However, the proliferation of negative ads can also contribute to voter cynicism and polarization, complicating the electoral landscape and affecting overall democratic participation.
