Based on the data of the presidential election survey published by the American National Election Research Center, this paper analyzes the methods and degree of political participation in American electoral politics and the correlation among media contact, political efficacy and political participation, and probes into the different influence and diachronic changes between traditional media and new media in political life. The results show that there is a significant positive correlation between traditional media exposure and internal political efficacy in specific political events. Meanwhile, the impact of online media contact on political efficacy has changed in the vertical direction. To sum up, there is significant positive correlation between media contact, political efficacy and political participation to a certain extent.
