Sometimes politics has the uncanny effect of mirroring the national psyche even when nobody intended to do that. This is perfectly illustrated by the rousing effect that Gov. Sarah Palin had on the Republican convention in Minneapolis this week. On the surface, she outdoes former Vice President Dan Quayle as an unlikely choice, given her negligent parochial expertise in the complex affairs of governing. Her state of Alaska has less than 700,000 residents, which reduces the job of governor to the scale of running one-tenth of New York City. By comparison, Rudy Giuliani is a towering international figure. Palin’s pluck has been admired, and her forthrightness, but her real appeal goes deeper.

She is the reverse of Barack Obama, in essence his shadow, deriding his idealism and exhorting people to obey their worst impulses. In psychological terms the shadow is that part of the psyche that hides out of sight, countering our aspirations, virtue, and vision with qualities we are ashamed to face: anger, fear, revenge, violence, selfishness, and suspicion of "the other." For millions of Americans, Obama triggers those feelings, but they don’t want to express them. He is calling for us to reach for our higher selves, and frankly, that stirs up hidden reactions of an unsavory kind. (Just to be perfectly clear, I am not making a verbal play out of the fact that Sen. Obama is black. The shadow is a metaphor widely in use before his arrival on the scene.)

I recognize that psychological analysis of politics is usually not welcome by the public, but I believe such a perspective can be helpful here to understand Palin
