I saw it and immediately concluded that Clinton was reflecting on how his presidency had differed from the ideal that Mulroney described. I don't think he was asleep.
Oops, looks like I had the wrong thing in my clipboard. Note to self - proofread before posting!
What strikes me is that Clinton couldn't even rise to this solemn occasion of the memorialization of a fellow past President, a moment of National history or the respect deserved by a grieving widow and family. He is worthless as a human being.
