Friend, all I can say is, you've got some serious misperceptions about Sarah Palin.
Perhaps you've bought the left-wing talking points about her, and have never taken the time to honestly review her twenty year record of accomplishment, nor read any of her speeches and articles. You certainly couldn't have read either of her books, if that's your opinion of her.
Let me ask you this: if Palin is such a lightweight, why does she enjoy such overwhelming support among well-informed conservatives, and why is she so relentlessly attacked by the left-wing establishment?
If she's such a lightweight, how on earth did she ever win election to the Alaska Governorship, and why did she hold the highest approval rating of any Governor of the fifty states?
If she's a lightweight, you've got to ask yourself - why there is so much speculation about her possibly running for the nomination?
Lightweights do not achieve such things, my friend.
You can't be serious...??????
