Insiders, Outsiders, and Voters in the 2008 U.S. Presidential Election

In 2008, both Barack Obama and John McCain repeatedly talked about "reform" and "change" on the campaign trail, presumably believing that voters would respond to a president who could challenge the established way of doing business. The authors gauge the significance of "reform" politics in 2008 through two analyses. First, they estimate a two-dimensional issue space, paying particular attention to the possibility of a reform/establishment dimension. Second, they consider whether voters (1) preferred reform candidates, and (2) saw Obama or McCain as credible reform candidates. The data indicate the existence of a reform-establishment dimension. However, neither Obama nor McCain effectively convinced voters that they were reformers.
