Palin has gripped the American imagination in a way that seems designed to burrow into our dream lives. Palin's supermom abilities provoke envy and anxiety in women, especially other working mothers.

A couple of conservative men I know have mentioned that they've been having sexual fantasies about the Alaska governor. I'm sure they're not alone.
