From The New York Times:
a team of political scientists is arguing that people's gut-level reaction to issues like the death penalty, taxes and abortion is strongly influenced by genetic inheritance. The new research builds on a series of studies that indicate that people's general approach to social issues - more conservative or more progressive - is influenced by genes.
If cons hate science so much, maybe we liberals should be focusing our efforts on genetic engineering. Who said communism was antithetical to human nature?
