David Benjamin might have tapped into the psychology:
Sooner or later, words fail everyone. This goes double for Sarah and her faithful. Sarah Palin is the voice - and the embodiment - of the inarticulate.
When Sarah Palin says something that doesn't seem to make sense to most of us, her people - the tongue-tied and frustrated - understand perfectly, because that's exactly what they would have said, if only they could.
Of course, my view remains that a celebudoof role model doesn't equal "presidential." If a certain demographic of Americans need a role model, that's fine. Give her a reality show and let's move on.
