Obama can't take 45 minutes of tough questions, how did Clinton take 8 years of Ken Starr's investigation?

Remember in the debate, Obama complained about having the hard questions being asked to him. Because he just don't wants to spend time to talk about it, only wants let the fantasy talk tops over. He said once a year ago, he quoted, he would not talk about them unless he likes the question, then he will say something. He only wants to have easy ones. Everyone seems forgets that.
