Yeah, that review really missed the point. I don't think that the movie tried to say anything about the values of different political beliefs and ideologies. The whole point was that elections and campaigns are often more about image, charisma, presentation, looks, and other superficial qualities including appropriate gender/ethnicity/family situation, in other words, it's just like any other marketing/advertising campaign where you try to sell a product. Palin was an extreme example of where that can take you (but certainly not the only one).
