I saw the entire interview, and was suitably impresses with his answers. Even when he wasn't able to promise details, he had the concepts right. He simply sounds sincere and competent.
   He has used the last year or so to study issues and get more depth in the areas where it was suggested he didn't have full experience...and a president MUST be able to learn very fast on the job. He certainly had understanding of economic issues that McCain admits to being weak on.
