Impact of Gaffes on Voters

FiveThirtyEight has an interesting article about the impact of gaffes on voting and campaign finance. Nate Silver says that gaffes impact the media audience but not necessarily voters. According to him, Romney's "47 percent" comment only had a 1 percentage point swing in favor of Obama. But like Prof. Pitney said in class, even 1 percentage point is significant in such elections.
