Jonathan Haidt talks about differences between parties:
The results of thousands of respondents in several countries provides clear evidence for a divergence of importance placed on these five foundations of morality. Liberals’ value – Harm/Care high, then Fairness/Reciprocity, then a big drop to Authority/Respect and In-group/Loyalty, then least Purity/Sanctity. Conservatives’ value – Harm/Care lower than liberals but place it at the top of their lists as well. Authority is a close second followed closely by In-group/Loyalty, and Purity/Sancitity, with Fairness/Reciprocity at the bottom.
