Palin in not exactly stupid... she IS ignorant, and that, to my mind is worse. She is steeped in the worst sort of cultish religious silliness... added to a devotion to 'making a $$$' from whatever she does.(much like Bachmann) She make no effort to educate herself about the world in general and just follows a system which seems to be largely defined by her husband (much like Bachmann).

She attracts others who also think that way, and can make $$$$ just showing up and spewing the Tea Party line... with a few polished "palinisms" thrown in.
