Amos never mentioned 'being on holiday', or at least I didn't equate that post with any inference to Bush 'being on holiday'.

I think most people expect The President's job to be a 24/7 one.

But the fact that these statistics keep appearing, seems to imply to me that this is not, or should not be, normal behaviour for a man who has such a 'hands on' job as he has.

It also appears that GWB never actually read PDBs. Any of them. He apparently only had them summarised verbally to him.
Clinton, also apparently, used to kick everybody out and read them himself, in private.
