Objective. Past research shows that electoral context prompts changes in political trust. In the United States, data limitations confine this literature to status-quo affirming presidential elections. We extend previous research to unexamined contexts: elections with partisan presidential changes, midterm elections with shifts in congressional control, and nonelection periods. Method. Original panel data from 2004Original panel data from , 2005Original panel data from , 2008Original panel data from , 2010Original panel data from , and 2012 are used. Data were obtained from surveys administered to students enrolled at a large midwestern university. We compare context effects on trust and other political attitudes, and contrast trust levels among winners and losers in each context. Results. We find that trust is more malleable than most other attitudes in all periods; it is less stable in presidential elections than congressional elections; and there is no evidence of winner and loser effects. Conclusion. Our findings reveal the importance of political context in explaining the stability of trust by showing that trust levels are more changeable in certain contexts than others, specifically more changeable in presidential than in congressional elections. This article examines individual-level changes in political trust occurring in different U.S. electoral contexts. Scholars have long recognized that the political environment could affect citizen support for the political system-a concept also known as trust in government and generally measured by a question asking the degree to which the respondent trusts the federal government to do what is right (see Miller, 1974;Citrin, 1974 for a discussion of the meaning of the American National Election Studies [ANES] trust in government questions). Research examining the stability of trust across election periods has been limited, however, because the data necessary to identify whether election results reduce the support that people feel for the political system generally, or the federal government specifically, do not exist nationally. The ANES included pre-and postelection measures of trust in their 1972 and 1996 panel surveys, but the outcomes of these elections were identical in that they affirmed the status quo (an incumbent president serving under divided government). The ANES have not gathered panel data on trust in government at any other time, nor have other national surveys, and this has inhibited the specification of changes in trust brought about by political context, such as electoral outcomes that bring significant partisan changes to the presidency, Congress, or both branches.
