I noticed when Mr Obama was walking thru the hall in the Capitol before he actually went outside - that he looked absolutely terrified. He didn't have that smile or look of confidence that he always has. I felt rather bad for him at that moment.
Yes, I noticed that, too. I don't know if he was really terrified, or if he just felt the weight of his responsibility in that moment, but he sure looked like he wasn't feeling well.
