Sarah Palin has achieved her status by being honest and true to herself. She has used wisdom and common knowledge in order to get real Americans to listen to her. Sarah is a self-made force.
On the other hand, that Barrack Obomo character is a product manufactured by some left-wing secret committee made up of wealthy anti-American men. Obomo is ignorant, arrogant, emotionally immature and unprepared, unintelligent, insincere, funny looking, inarticulate, lazy, and mostly just a goofy puppet.
The left has every reason to lie about and slander Sarah Palin. She is the real deal. That is something a "successful" leftist cannot afford to be, which gets them Barrack Obomo as their front man/puppet.
