@Gala,
Gala, I remember a study done some decades ago that proved that presidents have been elected on "looks" and nothing else. I guess most people would call it "charisma," but it's way beyond the ability to be president of the US that involves so much more. We also know that it requires more than "intelligence" to be a good president, but we also know that without intelligence, any president can sink our country into a great recession - or worse. Economics is not an easy subject, because it isn't science; it also takes good luck and guessing at the right actions to take at the right time.
It's way beyond Palin; she has contradicted herself on TARP and the stimulus plan. Everybody has 20/20 vision after time has elapsed, except for some conservatives who keep blaming Obama for the current loss of jobs.
