The Effects of Political Advertising

The Harsh tone of political advertising, the often controversial techniques employed by political advertisers, and the fact that the competing claims made in campaign ads are beyond review, have raised questions about the goals of political advertisers. Many critics have suggested that political advertisers seek votes at any cost, even including a degraded sense of public regard for the candidates and the electoral process. Perhaps the amount of negativity features in political campaigns is designed t shrink the market rather than increase the sponsors relative share. Discouraging people from voting is much more feasible than persuading supporter of one candidate to vote for the opponent.

Today's Facts:
Unlike commercial advertisements, political advertisements are not subjected to the same regulatory policies. Therefore, one must be mindful as to how these commercials weigh on our voting decision.
