Abstract
A large body of research has examined the advantages and disadvantages of California’s top-two primary system. Initial research indicates that voters, parties and candidates are still adjusting to the new system. However, few research studies examine why some primaries produce two candidates of the same party. This research set out to determine the relationship between same party general elections and the population of minority groups in a district. The findings of this study indicate a significant relationship between a district’s minority population and the probability of same party general elections, but only in certain types of districts.
