For years Arkansas voted for Republicans in blue. From post-Reconstruction to industrialization and civil rights, Arkansas maintained a conservative ideology while aligning itself with the Democratic Party. In the late 20th century, the South shifted to the right, but the Natural State stayed loyal to the left and its traditional voting tactics. It would not be until the 21st century that Arkansans would recognize that the national Democratic Party did not represent their views. By the 2014 midterm elections, Arkansas’s long time conservatism, newly developed industry and demographic changes coalesced into a partisan change. Arkansas embraced red.

This thesis provides a comprehensive analysis of midterm U.S. House elections using a multi-level research design. At the aggregate-level, multiple regression analysis is used to examine the variables that affect seat loss for the president’s party. This integrates, updates and extends the extant literature of the topic, and offers a means of explaining and predicting seat losses by the president’s party in the U.S. House. To further probe the findings at the aggregatelevel, the thesis develops a pooled cross-sectional model of individual-level vote choice in midterm U.S. House elections using data from the American National Election Studies (1982- 2002) and the Cooperative Congressional Election Study for the 2006 and 2010 midterm elections. Findings suggest that variables measuring the performance of the economy and realignment of the South toward the Republican Party affect seat loss at the aggregate level. However, at the individual level, economic evaluations exerted little influence on vote choice, above and beyond party identification, although perceptions of the national economy did appear to influence vote choice in the 2006 and 2010 elections. Future research might incorporate the strategic politician thesis into the explanatory scheme and move the analysis to elections for other political offices, such as U.S. Senate elections as well as state legislative and gubernatorial elections.

The thesis aims to discuss a theoretical framework of the U. S. congressional midterm elections and specify their fundamental funtions and importance. The thesis analyses the transformation of midterm elections as well as their effects on the political system with a special focus on the period 1990-2008. Following the analysis of particular midterm elections, it concludes that some of the theoretical premises need to be revised.
