Media markets and politicians involved in scandals

In this paper, I study whether TV coverage helps voters punish politicians involved in a scandal. Specifically, I compare the vote shares of U.S. senators implicated in scandals from 1970 through 2000 in two different types of media markets: in-state and out-of-state. An in-state media market is centered in a given state, and an out-of-state is located outside a given state. Therefore, the media consumers in an out-of-state media market receive news contents that focus on neighboring states' politicians. I find that U.S. senators implicated in scandals receive smaller vote share in in-state media markets. The results suggest that better access to political news helps voters make more informed decisions. (C) 2016 Western Social Science Association. Published by Elsevier Inc.
