A Question on Political Psychology

According to a well-known article in Psychology Today, thought of death can make people conservative:

As a follow-up, Solomon primed one group of subjects to think about death, a state of mind called "mortality salience." A second group was primed to think about 9/11. And a third was induced to think about pain—something unpleasant but non-deadly. When people were in a benign state of mind, they tended to oppose Bush and his policies in Iraq. But after thinking about either death or 9/11, they tended to favor him. Such findings were further corroborated by Cornell sociologist Robert Willer, who found that whenever the color-coded terror alert level was raised, support for Bush increased significantly, not only on domestic security but also in unrelated domains, such as the economy.

Question: What is the effect of thinking about birth? Considering that parents (or married people in general) are more likely to be conservative, maybe thinking about birth causes conservatism as well. (That may explain why opposing abortion is a right-wing issue.) One of my theories is that conservatism is linked to a tendency to think about time. Thoughts of both birth and death would lead to thoughts about time and then to conservatism.

On the other hand, considering their attempt at a control group, maybe thoughts of pain produce liberalism.
