I agree that judgments about intelligence are inherently subjective. In this case, the subjective opinion is that of interviewers for the National Election Studies, a nonprofit entity funded by the National Science Foundation. NES has been conducting interviews periodically since 1948. After conducting each interview, usually a lenthy one conducted in person, the interviewers are asked to rate the "apparent intelligence" of the people they just interviewed. Republicans

I don't know if there is a chart showing conservatives are smarter than liberals, but there is a chart showing that Democrats are only about 75% as likely to be assessed as having fairly or very high "apparent intelligence." The chart is in Democrats and Republicans - Rhetoric and Reality, a lengthy book that compares Democrats and Republicans in every possible way, such as lifestyles, intelligence, education, charitable giving, taxes, welfare, happiness, and citizenship.
