Is anyone else as disturbed as I am that Barack Hussein Obama has ONLY 2 years experience?

He was elected Senator in 2006. How does this qualify him? The President is the leader of the free world, Commander and Chief of the most powerful military and presides over the one of the largest ecomomies in the world. How is his 2 years of being a Senator experience enough for that? Both Hillary and McCain have so much more experience in every aspect. It's scary to me if Obama actually wins.
