“There’s a good chance that Palin will peak early and the voters will be tired of her by 2012.”
I’ve met her and her husband, and trust me... America is not going to get tired of her. No way, no how.
I've heard Sarah Palin speak in person and I can endorse your judgment--you just want to listen to her for as long as she can speak without falling over.
Authentic people don't "Peak."
