why women are (far less likely) to be Libertarian than men

A bunch of possible answers to an interesting and important question. In no particular order...

1.) Women generally feel more vulnerable and embrace govt as a means to various ends. 

2.) Women generally tend to be more paternalistic in their personal relationships and may extend this to governance.

3.) Women generally pay less attention to politics and reasonably settle for one of the two major parties.

Others? Is Gen 3:16 in play here?
