This article is a short form of a fantastic book by psychologist Jonathan Haidt. A lib in the beginning, he started studying conservatives and morality and ended up liking and respecting, and valuing, the conservative approach to morality. Some initial excerpts, link to article at bottom:

WHAT MAKES PEOPLE VOTE REPUBLICAN?

What makes people vote Republican? Why in particular do working class and rural Americans usually vote for pro-business Republicans when their economic interests would seem better served by Democratic policies? We psychologists have been examining the origins of ideology...

...we have refined our diagnosis: conservatism is a partially heritable personality trait that predisposes some people to be cognitively inflexible, fond of hierarchy, and inordinately afraid of uncertainty, change, and death. People vote Republican because Republicans offer "moral clarity"—a simple vision of good and evil that activates deep seated fears in much of the electorate. Democrats, in contrast, appeal to reason with their long-winded explorations of policy options for a complex world. ...

Diagnosis is a pleasure. It is a thrill to solve a mystery... But with pleasure comes seduction, and with righteous pleasure comes seduction wearing a halo. Our diagnosis explains away Republican successes while convincing us and our fellow liberals that we hold the moral high ground.

Our diagnosis tells us that we have nothing to learn from other ideologies, and it blinds us to what I think is one of the main reasons that so many Americans voted Republican over the last 30 years: they honestly prefer the Republican vision of a moral order to the one offered by Democrats. To see what Democrats have been missing, it helps to take off the halo, step back for a moment, and think about what morality really is. ...

This is the first rule of moral psychology: feelings come first and tilt the mental playing field on which reasons and arguments compete.If people want to reach a conclusion, they can usually find a way to do so. The Democrats have historically failed to grasp this rule, choosing uninspiring and aloof candidates who thought that policy arguments were forms of persuasion.

...I would say that the second rule of moral psychology is that morality is not just about how we treat each other (as most liberals think); it is also about binding groups together, supporting essential institutions, and living in a sanctified and noble way.

When Republicans say that Democrats "just don't get it," this is the "it" to which they refer. Conservative positions on gays, guns, god, and immigration must be understood as means to achieve one kind of morally ordered society. When Democrats try to explain away these positions using pop psychology they err, they alienate, and they earn the label "elitist." But how can Democrats learn to see—let alone respect—a moral order they regard as narrow-minded, racist, and dumb?
