I saw it last night, and think I see it again watching the CSPAN tape of the speech.
I think Bush is fighting tears when he talks.
Check the tape just before 57:56 minutes in. I think for just a second he loses composure and then it's back again. But I would bet money that he was fighting tears....or at least a sneeze. So, is Bush showing his "softer side" or behaving like a "girlie-man."
