Deceit, diversity, or mobilization?

What explains President Bush's increased vote in the State of Florida in the 2004 election? A common perception is that implementation of electronic voting machines and a surge in GOP registration increased Bush's vote margins relative to the 2000 election. In this paper we offer an alternative explanation: massive Puerto Rican immigration combined with successful Republican mobilization of this group explains about 14% of the increase in Bush's margin of victory—approximately 50,000 votes. Scholars’ failure to account for intra-ethnic diversity, by employing a “panethnic” approach that treats Latinos as having identical political preferences, leads scholars to overlook the important role of Hispanic subconstituencies in the 2004 election.
