Wow! I've just seen the future...and it's Jon Huntsman. Huntsman is retiring as Ambassador to China, has been effective governor of Utah and is going to run for President as a Republican. He is very impressive, as you can easily see from this video clip of an interview he had with Charlie Rose.And here is his Wikipedia article.
Huntsman is Mitt Romney without Romney's negatives. I think he's going to shock the Republican field as soon as he jumps into the race (assuming he does).
