LSA US Centre online
With the rise in prominence and influence of conservative politicians such as Senators Ted Cruz and Rand Paul in recent years, the role of the Tea Party in U.S. politics has become more and more important. In new research, Caitlin E. Jewitt and Sarah A. Treul examine how the presence of a Tea Party candidate – a divisive election – affects general election results compared to elections that are simply competitive. They find that competitive primaries increase turnout rates, but do little for a party’s election result. They also find that while the presence of a Tea Party candidate in the general election means that the Republican Party performs 1.7 percent better than expected, when there had been a competitive primary, there is no additional effect...

2014 ABSTRACT: We examine the effects of competitiveness and divisiveness in the 2010 congressional election, as the emergence of the Tea Party resulted in many competitive Republican primaries and highlighted significant divisions within the party. We find that ...
2012 ABSTRACT: In the current era of polarization, bipartisanship between a president and senators of the opposite party seems unlikely. Yet, we expect that given a senator's desire to please his constituents and ensure reelection, if a president is popular with constituents in a ...
2011 ABSTRACTS: Students of linguistics and psychology demonstrate that word choices people make convey information about their emotions and thereby their intentions. Focusing on theory from these related fields we test whether the emotional content of Supreme Court justices' ...
2009 ABSTRACT: This paper tests whether Supreme Court justices tip their hands at oral arguments. Specifically, we test whether, when justices ask more questions of one side, that side is more likely to lose their case. The findings support the theory; namely, when justices ask more ...
2008 ABSTRACT: This article examines the role progressive ambition plays in the US Senate. I analyze the effect ambition has on party loyalty in the upper chamber. The theoretical argument is that senators with ambition for higher office are more loyal to the party than ...
