Political scientists have long noted that congressional elections are often uncompetitive, often extremely so. Many scholars argue that the cause lies in the partisan redistricting of congressional districts, or “gerrymandering”. Other scholars emphasize polarization created by a fragmented news media, or the candidate choices made by a more ideological primary electorate. All these explanations identify the cause of party-safe elections in institutions of various kinds. This dissertation, by contrast, presents a structural explanation of uncompetitive elections. My theory is that population composition and patterns of migration are significant causes and predictors of election results in Florida. I test this theory empirically by comparing the predictions from four hypotheses against aggregate data, using the county as the unit of analysis. The first hypothesis is that Florida can be divided into clearly distinguishable, persistent partisan sections. This hypothesis is confirmed. The second hypothesis is that Florida voters have become increasingly partisan over time. This hypothesis is confirmed. The third hypothesis is that the degree of migration into a county predicts how that county will vote. This hypothesis finds some confirmation. The last hypothesis is that the degree of religiosity of a county predicts how that county will vote. This hypothesis is confirmed. By identifying the structural causes of party-safe elections, this study not only contributes to our understanding of elections in Florida, but also sheds light on the current polarization in American politics.

Thesis advisor: Marc Landy / The election of 2000 was the most tumultuous election of the present day - an election that involved numerous lawsuits and was ultimately decided by the votes of Supreme Court Justices. What many Americans do not know or remember is that there was another election in 1876 with largely similar circumstances - disputed electoral votes (in Florida again) and a winner (Rutherford B. Hayes) produced by a Supreme Court Justice. This essay aims to examine these two elections in detail in order to demonstrate the flaws of the U.S. Constitutional system and the different manners in which they were resolved. The second part of the essay aims to determine whether the purported illegitimacy of the two winners (Hayes and Bush) affected their respective presidencies. / Thesis (BA) — Boston College, 2005. / Submitted to: Boston College.

Since the early 2000s, Interactive Voice Response (IVR) has become a widely popular method of conducting public opinion surveys in the United States. IVR surveys use an automated computer voice to ask survey questions and elicit responses in place of a live interviewer. Previous studies have shown that IVR polls conducted immediately before elections are generally accurate, but have raised questions as to their validity in other contexts. This study examines whether IVR polls generate measurably different levels of candidate support when compared to live interviewer polls, as a result of non-response bias owing to lower response rates in IVR surveys. It did so by comparing polling in 2010 U.S. gubernatorial and U.S. Senate elections that was conducted using both live interviewers and IVR. The findings suggest that in general elections, IVR polls find fewer undecided voters compared to surveys conducted using live interviewers. In primary elections, IVR polls can show larger support than live interview polls for a more ideologically extreme candidate who has high levels of support among more opinionated and engaged voters. Implications are that journalists and other consumers of polling data should take into account whether a poll was conducted using IVR or live interviewers when interpreting results. IVR polls may tend to over-sample more engaged and opinionated voters, often resulting in smaller percentages of undecided respondents, and higher levels of support for specific candidates in certain contexts. / Master of Arts
