Answer:
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.
