Funny, I remember him on the trail right up to the end...
He campaigned up until about 5 pm the nite before as I remember and went to texas where he did what candidates do, they spend election day with family, friends, vote and sit around. Al gore campaigned all nite long if you remember, he was crazed, he actually campaigned all election day if I remember, I could be wrong. But I do know he did an all nighter.
