Urgent! What are some limits on the media's impact on the behavior of the American voting public?

Another way media can influence policymakers is through shaping public opinion, which in turn, exerts pressure on policymakers to respond [13] ... Our objective is to better inform those considering the use of media interventions to influence health policy-making

Social media had no effect on belief accuracy about the Republican candidate in that election. The 2016 survey focused on campaign issues ... These results demonstrate that social media can alter citizens' willingness to endorse falsehoods during an election, but that the effects are often small.

Citizens learn about politics and government primarily from television and newspapers; these media outlets can influence voters not only through the slant of a particular report, but also merely by choosing which to stories to cover. This study measured the effect of receiving free subscriptions to either a liberal or conservative leaning newspaper on voters' political knowledge and opinions in the United States. Results demonstrated that neither subscription had an impact on voters' political knowledge, but that both subscriptions caused voters to increase their support for the Democratic presidential candidate. This suggests that the informational effect of news exposure was stronger than the effect of the slant.

Policy issue

Citizens learn about politics and government primarily from television and newspapers. These media outlets can influence voters not only through the slant of a particular report, but also merely by choosing which to stories to cover. Recent studies suggest that media exposure can have a sizable impact in shaping the public's political knowledge, attitudes, and behavior. However, these studies may have overestimated the impacts of media influence due to individuals' tendency to seek out information that agrees with their pre-existing views.

Context of the evaluation

Prince William County in northeastern Virginia lies just 25 miles from Washington, D. C. Here, the population is far enough away from the nation's capital so as not to be dominated by citizens involved professionally with politics, but close enough to be within the circulation of Washington's conservative and liberal newspapers. The Washington, D. C. metro area is served by two major newspapers, the conservative Washington Times and the more liberal Washington Post. The presence of a liberal and conservative paper serving the same region creates an opportunity to study the effect of media slant in a natural setting within a single population, which is subject to the same outside factors, such as political events and outcomes, and has a range of political leanings.

Citizens usually learn about politics through the media (television, newspapers, etc)
