Ground Campaign Project

 

Granted unprecedented access to Democratic campaign workers, Eitan Hersh and I unveil initial findings of the Ground Campaign Project (GCP), a research endeavor done in conjunction with Obama for America, NGP-VAN, and twenty-five state Democratic parties. The result of the partnership is a longitudinal study in which we interviewed nearly 4,000 campaign staffers, interns, and volunteers during the final six months of the 2012 campaign.  Our paper "Elite Perceptions of Electoral Closeness: Fear in the Face of Uncertainty or Overconfidence of True Believers" uses this data.

Segregation Plot

This is a plot of the Dissimilarity Index between African Americans and whites in states and major cities in the United States. The Dissimilarity Index is a common measure of segregation and I use it often in my research. It measures the proportion of one group that would have to move across areal units within a geography to achieve balance between groups across areal units. So, looking at the plot here, in Gary, Indiana, the most segregated major city in the United States with a Dissimilarity Index of almost .9, for African Americans and whites to achieve racial balance, almost 90% of African Americans would have to move to new Census Tracts. Data is from the 2000 Census

In this plot, the y-axis is population in units of 100,000, the x-axis is the Dissimilarity Index, the blue dots are cities (Metropolitan Statistical Areas) and the orange bars are states.

Interviews on intergroup attitudes 

As part of my book project The Space Between Us: Social Geography and Politics., I am conducting interviews of citizens, from elected officials to ordinary voters, about their perceptions of space and intergroup relations.  

I have completed interviews in Boston, Chicago, Los Angeles, and Phoenix. 

In fall 2009, I conducted a series of focus group sessions with African American registered voters in the Crenshaw neighborhood of the city of Los Angeles. My analysis of the interviews is ongoing. 

 

Facial Competence and Vote Choice

The link below is to a figure with the distributions of "facial competence" among candidates for the the United States House of Representative in 2004 and Senate from 1992-2006, as measured by Matthew Atkinson, Seth Hill, and Ryan Enos using the method described in "Candidate Faces and Election Outcomes: Is the Face-Vote Correlation Caused by Candidate Selection?" (Quarterly Journal of Political Science 4 (3), pp 229-249). Note that the shaded regions of the distributions represent challengers. Competence Distribution

For an example of the instrument we used to generate these scores. You can visit Seth's page. This is a mockup of the survey, with which we presented participants with randomly drawn pairings of candidates. Survey Example

 

 

Field Experiment on Pivotal Voting

With Anthony Fowler, I launched a field experiment around the special election for the 6th Worcester District for the Massachusetts House of Representative on May 10, 2011.  This election ended in an exact time, allowing a unique opportunity to study the influence of pivotality in decisions to vote.  The article is here (2014, Political Science Research and Methods)..

We describe the research design and details here.

 

Field Experiment on Racial Threat

I conducted a field experiments during the June 3, 2008 Statewide California Primary and the November 4, 2008 General Election. To see an example of the treatment used, click here.  This is reported in my book manuscript The Space Between Us: Social Geography and Politics.

 

 

 

Natural Experiment on Spatial Impact and Racial Threat Using Chicago Housing Projects

I have tested theories of Spatial Impact and Racial Threat using the destruction of housing projects in Chicago as a natural experiment. The article is here (2015 American Journal of Political Science). A map of public housing projects in Chicago and Congressional Districts is here and Aldermanic Wards is here.
