Why do Americans like Hilary and Obama?

I am a die hard Bush supporter, and I have been ever since 2001. But, for the life of me, I cannot understand AT ALL why ANYBODY would vote for Hilary Clinton or Barak Obama. Obama has virtually no political experience, and Hilary could drive many small companies and poor people out of business, not to mention that national security would disappear if they were elected. And if you are pro-life, they are the opposite! Well, at this point I can't see anybody being to much of an obstacle between Hilary and the White House, so why (my fellow Americans haha) would Americans vote for Hilary or Obama?
