Why do Hollywood celebs hate Palin's lack of experience and yet applaud Obamas. What really is Obama's appeal?

now now, Obama has 143 days of actual senate experience before he launched his presidential exploratory team. Isn't that enough experience??? I know palin has only been a Governor but really it shouldn't matter. A ton of past presidents weren't even Gov's. Lets see, Bush, ah sorry Texas. Clinton, ah sorry Arkansas......
