What is not to be expected of that?
Politics is the sum of many, many attributes. Not all of them are forcefully tied to intelligence, honesty, altruism, etc as a good portion of us would like.
Things like good communication skills, presentation, charisma, resolve, etc are undeniably key in swaying the electorate's opinion.
For example, Palin has exceptional charisma and presentation, but her communication skills are incredibly bad. She could have the best intentions in the world, but if you can't communicate them, then you're toast.
Now, it's a lot easier to fix the communication skills than try to change yourself into a charismatic person (see McCain, John). So she definitely has that going for her. That said, she also needs to work more on policy (also doable) and to figure out how to get the party together, and not splintered. I don't think she figured that one out yet.
