For their study, titled "The Dating Preferences of Liberals and Conservatives," the research team randomly sampled 2,944 profiles from a popular Internet dating site, and examined the dating preference of users who identified as either liberal of conservative.
The data allowed them to compare the way each dater described themselves on a number of dimensions, including race and ethnicity, religion, and the desire to have children, to the characteristics of their ideal date.
By and large, liberals and conservatives do not differ in their tendencies to seek out a partner that shares their characteristics. Overall, conservatives appear to be somewhat less accepting of dissimilarity.
For example, conservatives are more likely than liberals to desire a date who shares their current relationship status, and conservative males are more likely than liberal males to want to date a female of their own race.
Overall, regardless of ideology, daters want a partner that shares their characteristics.
