Principled or Opportunist? Perceptions of Arlen Specter and His Party Switch During the 2010 Midterm Election

While the literature on party switching identifies the reasons that politicians switch parties and the negative electoral consequences of doing so, it does not adequately explore why these consequences exist. To accomplish this task the authors look at citizen responses to party switching. The authors explore perceptions of Arlen Specter and his change in party affiliation during the 2010 midterm election by using original survey data gathered from residents of Pennsylvania's 3rd Congressional District. The authors posit that the information environment created by the parties, candidates, interest groups, and the media during the election frames the switch as both principled and opportunistic. The authors find that partisanship plays a large role in the frame that is accepted by citizens and that those frames subsequently influence their views of the candidate's favorability.
