Parties,Institutional Control,and Trust in Government*

Objectives. Partisanship should affect evaluations of Congress just as it affects evaluations of the president, and these institutional evaluations should affect political trust. We argue that the relationship between partisanship and trust is dependent on partisan control of Congress and that much of party identification's influence on trust occurs indirectly through approval of governmental institutions. Methods. Using data collected before and after the 2002 congressional elections by the Center for Survey Research and Analysis at the University of Connecticut, we examine changes in frequency distributions and mean values for trust and institutional approval. We use multivariate regression models and a path model to estimate the causes of political trust and self‐perceived change in trust. Results. We find evidence that party control of government and party identification are important in explaining trust and institutional approval. The Republican takeover of the Senate led Republicans to evaluate the Senate more favorably and to become more trusting of the government, while having the opposite effect on Democrats. Conclusions. The changes in approval and trust resulting from the 2002 elections suggest that at least some segment of the population is cognizant of changes in the political environment and updates its views of government when the political environment changes.
