General political knowledge is a central variable in American politics research. Individuals with high political knowledge exhibit behaviors that are consequential to a well-functioning democracy, including holding more stable political opinions, exhibiting greater ideological constraint, knowing more about political candidates, and being more likely to vote correctly. In this paper, we examine whether the internet revolution, enabling citizens to look up anything at any time, has changed the relative importance of political knowledge in American politics. We show that important generational differences exist between Americans raised during the broadcast era and Americans raised with the presence and accessibility of the internet. Internet access can be a substitute for political knowledge stored in long-term memory, particularly among this younger generation, who may be relying on the internet to store knowledge for them.

This paper evaluates the influence of online news consumption on attitudes toward the European Union in a context of protracted economic crisis. Using data from the 2011 Irish National Election Study, we combine location-specific information on broadband availability with respondent geo-location data, which facilitates causal inference about the effects of online news consumption via instrumental variable models. Results show that Irish citizens who source political information online are more prone to blame the EU for the poor state of the economy than those who do not. There is evidence of preference reinforcement among those with negative predispositions toward the EU, but not among pro-EU citizens. We complement this analysis with a study of voting behavior in the European Fiscal Compact Referendum, employing a similar methodological approach. The results from this second survey confirm the anti-EU influence of online news consumption among Irish citizens, although evidence suggests a pro-EU effect among voters who browsed the website of the politically neutral Irish Referendum Commission. Our paper contributes to the literature on public opinion, the EU, and political attitudes in times of crisis. [ABSTRACT FROM AUTHOR]
