I would watch this, at least once. By all accounts Coulter is insincere and takes these positions because of the money they bring her in book sales etc., while Bachman is a True Believer, and Palin is sort of in between (she probably mostly believes but I sense that she isn’t asking herself any difficult questions either). So watching the interactions, especially as Coulter has to practically physically restrain her eyes from rolling out of her head at the stupidities uttered by the other two, could have some entertainment value.
As an alternative, though, Colbert Report seems like a good fit. Sort of a stealth education for the Fox audience.
