Values comprise all precincts and data used in the voter turnout model. The second stage model only uses 739 observations. A reduction in data occurs due to the lack of voting in some precincts. No substantive differences exist between the descriptive statistics. For the cities present, 13.8% (102) come from Portland, 19.8% (147) from Wichita and 66.31% (490) from San Antonio.
