You equate "down to earth" with "stupid", and that is absolutely not the case. You don't like "folksy" - that's fine. You're certainly not alone - most people throw over someone who's real in favor of a slick orator and showman. That's how we got Bill Clinton. And Barack Obama. I, on the other hand, appreciate a real person with a real life and a real family, who didn't come ready made with glib non-answers and a wardrobe full of power suits.
Sarah Palin isn't stupid. She didn't "come across" as stupid. You think she's stupid because that's what the media brainwashers told you to think. And again, you're not alone and are most definitely the norm. Most people think what the media tells them to think.
